Data from the Equine Injury Database continues to grow.




According to the analysis for the two-year period, the catastrophic injury rate per 1,000 starts on dirt was 2.14; on turf, 1.74; and on synthetic surfaces, 1.55.

... the prevalence of fatality in 2-year-olds continued to be significantly lower than older horses racing on dirt surfaces, but on synthetic or turf surfaces, there was no statistically significant difference in the prevalence of fatality between 2-year-olds and older horses.

Hmm, there's a topic we've never discussed: the effects of fasting on the handicapping process; and whether post fasting binge eating has a different effect than say binge drinking, unrelated to fasting. But, those would probably belong under General Handicapping Discussion.

No, we're opening the can of worms that is 'study shows synthetics safer.'

The point about 2yos having a lower incidence of injury than their elders on dirt, but not synthetics is interesting. I hope they expound on that in the days to come.

Also, the two articles I've seen don't mention it, but I seem to remember from the releases on the first year's data, that they were seeing a general difference between 'fully intact males' and everyone else, with them testosterone laden laddies having more injuries than females and geldings. I wonder if that still exists in the larger sample.

I know why the results came out like this. Sound horses race better on artificial surfaces so they eventually run on them, while horses with infirmities run better on dirt tracks. Of course the more you race unsound horses, the more likely you are to have a breakdown.

Horsemen care about deaths, but they also care about injuries that take horses out of commission and force owners to pay bills for months to get that horse back to the races.

Any list on synthetic injuries that did NOT result in death?

I didn't think so.

Couldn't that be inferred by starts per horse. Compare starts per horse in California and Woodbine with starts per horse at Philly and Penn. Don't include any horse that ran on two types of surfaces within the year.

Who says there are safer? The difference is minimal, and I think overall you have a much higher class of horses racing on synthetics that dirt when you consider ALL tracks in this country.

Minimal difference? Do you even know what statistically significant means?

I don't think that TP, PID, GG, AP are high quality tracks either. And I am not sure why these lower quality animals would be more prone to breaking down. I know it's accepted as conventional wisdom, but I have my doubts about that theory.

The foundation of the track plays more into it than anything else. Some of these tracks have not repaired their foundations since they were first installed. This is a B/S argument. Its like saying a condo that was built two years ago requires less maintanance than a condo built 80 years ago. You could put anything you want on the top layer...its the underlying layers that are important to the integrity of the surface as far as true safety is concerned.

Thanks FB


Difference does not seem significant amongst surfaces in US, but compared to something like UK (below 1.0 i believe) it does seem significant.


If i were the people looking to reduce those numbers i would be looking very hard at the use of Drugs, the violators and pre-race inspections now.


If the problems Life at Ten was having can slip through net, then i'm sure a lot more worse cases do at a lower level.

There seems to be more Drug violations at the lower end, which suggests there may be more issues with soundness down at the lower quality level. A more "freindly racing surface" will help mask soundness issues and help reduce numbers.

There are more drug violations (=absolute number) at the lower end because there are simply more horses at the lower end. The breakdown rate is a proportional number.

I believe it's a corallary GM10, just like i think you can conclude synth numbers are lower due to a more freindly (less stessful on joints and muscles) race surface.

Yes, I know what it means. What I am saying is that it isn't significant, because they didn't include at least one very important factor, and actually a few.

Sure, TP, PID, GG, and AP are not top tier tracks, they are mid level. However, they are light years ahead of many dirt tracks that are included in the study. Do you want a list?

It doesn't even touch on the fact the dirt tracks are much older. Lets see how the new Santa Anita surface does.

The significance applies to the hypothesis ('Fatality rates are the same on both surfaces') they tested. You cannot deny that. As they suggest themselves, they will be able to do further analysis as they collect more data.

I don't have very high expectations for SA. I might be fine the first months but I expect the number of fatalities to go up after that.

It is only a matter of time before they have enough data for that. Until then, I accept the conclusion as it is: overall, they are safer. Maybe there'll be certain area's where they are not, but that is pure speculation at this point.

Oh I don't know, to save horses' lives perhaps? I'm not a horse but if I was, I reckon I'd prefer a hind leg injury over dying.

The only way to save lives is to stop racing. Arguing over half a horse per thousand starts when there is no way to know if it is only the surface just seems silly. There are way too many factors involved to know.

Oh, and if the study was reversed, it would clearly prove dirt is safer because of the other factors we mentioned, so certainly they would be mentioned.

I'm not confusing anything. I know that horses break down at a higher rate at cheaper tracks. I also know that the overall class level of synthetic surface tracks is well above those of dirt tracks, on average.

I also know that horses break down at a higher rate on older tracks with older bases than at newer tracks with newer bases.

I also know that the synthetic tracks are a lot newer and have much newer bases than dirt tracks.

Please, tell me where I'm wrong.

Scollay, during a meeting with the press after the presentation held at Keeneland in Lexington, noted racetracks participate in the EID on the premise individual track data won’t be made public. It’s up to each track to decide if it wants to release numbers.

You are dead on on all of these things. I couldn't find the whole report on the web, but through Paulick I found a two page appendix/addendum which had the graphs of the data cited. Nothing is controlled for except age and surface. The numbers and significance testing they cite is correct, but this study is way too basic and ignores other potentially infuential variables, many of which you cite. And it very well could be for exactly the reasons you cite, that the surface has nothing to do with it but the differences are being driven by other factors.

There are enough observations here to do a much better statistical analysis on this where one could have included variables such as age of track, purse of race and horse age along with dummy variables for track type and surface condition. Should do some sort of probit/logit style model which would estimate the probability of breakdown given all these factors and then test to see if the coefficients on the track type dummies are significantly different from zero or from each other.

In any case you don't need the stats. For flat racing the only place where you notice horses breaking down during races is the USA. No need to bury your heads in the sand (or should that be dirt) on this one. The breakdown rate on dirt in the USA is higher than most other racing countries

The significance applies to the hypothesis ('Fatality rates are the same on both surfaces') they tested. You cannot deny that. As they suggest themselves, they will be able to do further analysis as they collect more data.

I don't have very high expectations for SA. I might be fine the first months but I expect the number of fatalities to go up after that.Surely you must understand these statistics are too biased to be meaningful in any way shape or form.

As others have rightfully pointed out:

1) These synthetic tracks are all relatively "new" with brand new foundations, thus making comparisons with dirt tracks that are much older meaningless. Wouldn't a statistically significant study limit comparisons to dirt tracks of similar age to these synthetic surfaces?

2) Synthetic tracks have mostly been installed at upper class institutions, with few exceptions. Higher quality horses running at these synthetic tracks overall will bias the breakdown statistics when compared with dirt tracks like Charles Town, Mountaineer, Penn National and all other cheap dirt tracks. Wouldn't a statistically significant study limit comparisons to dirt tracks of similar class?

There is just no point in debating this (or indeed many other topics) with you. You show no academic curiosity, no desire to discover new knowledge, you just start from what you 'know', and defend that position until the end.He's showing tremendous academic curiosity by completely destroying the very conclusion the data is making based on STATISTICALLY UNSOUND methods of data comparison.

The study is trying to make the reader come to a certain conclusion (that synths are safer) based on completely misleading information that hasn't taken into account some of the BASICS when it comes to track safety.

You seem to be the one that wants to ignore academic curiosity and take this report at face value. We're the ones lifting the rug and noticing how filthy it is under there...

Not at all, old boy. Wrt breakdowns, I think that medication plays at least as large a role as the surface in the number of breakdowns. Wrt unreceptiveness ... Charles, you show me the evidence of the theories put forward here, and I'll accept those theories. Until then they are mere speculation, some of which are deserving of further analysis (as I already stated).

I'll try another if you won't answer the first one. I would really like an honest answer to this. Why would I possibly share my hard work for nothing on a message board, the same work this "group" was probably foolishly paid well to "study"?

We've been down this road before. Believe what I say or don't, I don't care. I'm not posting to impress gm10.

Why not share it? What edge do you get from not sharing such data?

OK, just to keep gm on the run, I'll post the average North American purses by surface for all the thoroughbred races I have since 2004 through about a week ago:

AvgOfPurse Races Surface
$31,835.80 25025 Synth
$17,755.81 281190 Dirt
$36,806.63 33687 Turf

You think have purses that are significantly higher on the two "lower breakdown" surfaces might skew breakdown results, gm10?

How about using three vastly different sample sizes? That ok too?

You are still speculating at this point. Maybe i will see evidence if I keep reading through these posts?

12-17-2010, 05:21 AM

Compare 1.8 and 1.7 to 1.55


Seems all synthetic surfaces are not much safer than these two Dirt tracks

They are low level tracks. The low level tracks that are supposed to skew the dirt breakdown numbers upwards :bang:

Yes, the sample sizes are fine.

The purses ... what are you trying to prove here? Surely you realize that there is one gigantic missing link? You told us that having an older track base leads or lower quality of racing leads to more breakdowns. I must be honest, I am impressed that you seem to have data like track base age, but you still haven't presented your evidence.

If you have all the data ... age of the track base, quality of racing, number of breakdowns, then it must be fairly straightforward to back up your earlier statements.

'I know that horses break down at a higher rate at cheaper tracks. I also know that the overall class level of synthetic surface tracks is well above those of dirt tracks, on average.

I also know that horses break down at a higher rate on older tracks with older bases than at newer tracks with newer bases.

I also know that the synthetic tracks are a lot newer and have much newer bases than dirt tracks.'

No, I don't have track age in my database. It is obvious it could, and probably is, a factor though.

You want to pretend purse size and breakdowns aren't related. That I can prove. Surely you don't want to argue that point, do you? Do you want to argue that dirt racing is conducted, on average, at much lower purse levels than the other two surfaces in North America?

That doesn't even factor in that many dirt horses are racing for artificially inflated purses at racinos. You think cheap horses aren't drugged up and sent out with more risk to run for slots purses? That is limited on the other surfaces.

I will leave you with a quote regarding 'groupthink' from the book that I mentioned before. I think it sums it up well.

Deliberation in a groupthink setting has the disturbing effect not of opening people's minds but of closing them.'

I haven't followed this discussion closely, so sorry to ask you a question you've probably already answered, but are you of the belief that allowance-level horses are just as likely to breakdown as $5k claimers?

CJ I have to thank you. You are the one who finally made me write this query.

Also, I think it was Bruddah (could be wrong) who once pointed out that these cheap old-timers make it very clear that they won't run if something is wrong, which makes up for their intrinsically weaker muscles and bones. Turns out he could be right.

I was undecided up till now. I used to think not, then someone explained to me why it could well be the opposite. Now I think the latter person was right.

Somewhat flawed logic. The cheap claiming ranks (let's say $10k claimers and below) are comprised of horses that have always lacked innate ability (consistent with the above statement) AND classy horses that have problems that are tapped every other race just to run.

Maybe what is perceived as a lack of ability really comes down to not wanting run beyond certain pain thresholds (in some cases), which seems like quite a natural reflex to me.

In any case, the numbers are what they are. A myth has been dispelled. I think Charlie D is putting up the balloons for this one.

These are very close. So, I'll now break both down by purse and breakdowns:

OK.

I swear I'm not trying to be difficult, but with cheap animals, I think of the likes you see at Mountaineer Park or Turf Paradise. When you are talking NYRA and SoCal, you are already excluding the very bad animals.

As a consequence, the sample sizes are pretty low now, which makes comparisons less reliable. Depending on the hypothesis you are testing you might find one that suggests that there is a trend, but I suspect that you might have to get a little creative in order to succeed.

I don't think there is much in it, for dirt at least. There is too little data for the poly imo.

For completeness' sake, these are my results for all dirt/poly/turf starters since 2004. I don't see a clear trend, apart from the one that dirt is less safe for nearly every comparison you wish to make.

No it is you who is ignoring the class factor by focusing on NYRA and SoCal. The majority of horses could never compete at those circuits.

Do yourself a favor and add Finger Lakes to your data set. Doesn't look quite the same does it? The cheapest races are the safest now that you've actually included the bad animals.

I was comparing apples to apples. What does Finger Lakes have to do with it? What I posted showed that synthetics and dirt are very similar when using the same types of horses. There is no synthetic track to compare to Finger Lakes, not even PID is that bad.

However, even in your query above, there is a trend towards lesser breakdowns outside the lowest class. Why is that?

The majority of horses simply cannot compete at NYRA tracks, agreed? All those horses have just as much right to survive their race as the faster horses, agreed? So why not include them?

I honestly see no trend as the one you mention. I see a peak at purse level 2, and fairly flat percentages beyond that. I also see that bad horses seem to do alright when it comes to breaking down. That is clearly in contradiction to the general trend that you are convinced of.

Doesn't reply #124 show in a crystal clear fashion that when comparing dirt to synthetics between two top class operations (NYRA and SoCal...can't get any higher class of horses in the USA), the results are quite similar in terms of breakdown rate?

How can that be gm10? I suppose if we are to believe the statistics contained within reply #124, then we can conclude that the class of the racing operation has a lot more to do with breakdown rates than the actual surface being dirt or synthetic.

Don't try to avoid the real issue now. The missing link in your argument against the study is 'cheap = more likely to break down'. That is the context of the discussion.

If you take a broad view (see post 127), the conclusion is simply that there is no relationship between purse and level of breakdowns. You may have been tempted to believe the opposite by by looking at higher level tracks only (NYRA), but a simple addition of FL to your short list of tracks has made it clear that the narrow data set conclusions aren't reliable.

I was also wondering earlier if you had any comments on the much lower level of breakdowns on poly than on dirt, but we can save that for another time.

Comparing equal class tracks shows no discernable difference in the rate of breakdown despite two radically different main track surfaces.

I don't see it that way, but that is fine. Compare apples to apples and you see what I see, more breakdowns at lower levels, and similar breakdowns despite surface. I'm not sure how mixing in FL with NYRA accomplishes anything.

Being representative of the entire population is exactly what's wrong with the original study. The "entire population" is skewed towards high class horses racing on synthetic surfaces, and lower class horses racing on dirt surfaces.

When looked at on equal footing, as CJ's example shows, there is minimal difference between the two surfaces when it comes to breakdown rate.

Correct me if I'm wrong but the study is not about NYRA horses, but intends to look at the entire horse population, from top to bottom. Hence NYRA/SoCal is not a representative sample.

Then why doesn't it apply to the entire country? Why are the real cheap horses in NY so much better off? Do you not think that a simple extension of that class/breakdown relationship would result in more breakdowns at FL?

Maybe the medication rules related to tapping a horse are more stringent in NY (must be done earlier) than in other states, preventing questionable horses from making it to the track in the first place? Would that explain it?

Let's find a sensible solution to this.

CJ argues that the study is unreliable because there are no really bad synthetic tracks. Fair enough, that is worth investigating, but he is making the same mistake in his efforts by only looking at tracks that are among the best in the country. That is not where 90% of the races take place, and hence we can't extrapolate those conclusions (assuming there are any).

So I suggest that for each synthetic track, we try to find an equivalent on the dirt. This way we can hopefully settle on a set of tracks that are of comparable quality, and do the breakdown analysis on both groups.

I'll take a stab at it just to get things going, please add your suggestions if you have any and hopefully we'll come to a set of tracks that we can agree on.

Del Mar (average purse 47K) - Saratoga (average purse 72K)
Santa Anita (40K) - Belmont Park (49K)
Hollywood Park (34K) - Aqueduct (33K)
Golden Gate (14K) - Tampa Bay (14K)
Keeneland (51K) - Churchill Downs (71K)
Turfway Park (13K) - Finger Lakes (12K)
Arlington Park (23K) - Hawthorne (16K)
Presque Isle Downs (23K) - Penn National (19K)
Woodbine (50K) - Fairgrounds (30K)

I hate to get into this thread because the fact that when Santa Anita went to dirt (about 90% sand (two kinds) and 10% clay it signaled the end of synthetic surfaces at serious race tracks.

It's kind of funny that the articles are coming out right now trying to revive this crap. Didn't Nicholson just go to Equibase from Keenland? Keenland is the mothership for this junk. They own a piece of Polytrack along with Martin Collins International.

This is about money and ideology. There shouldn't be any grade 1 or grade 2 races run on synthetic surfaces and there never should have been until after they were tested for a few years. This sh*t has caused nothing but problems when it comes to the road to the Triple Crown or HOY. Good riddance.

This is a post from a person who goes by Claimboxx who follows California racing as close as anyone;


A few things to consider and remember...

1) Horses are given a more thorough pre race exam than ever before...This, more than synthetics, has lessened the breakdown rate.

2) There are fewer fatalities, but more career ending injuries, i.e. soft tissue, broken legs behind than there were on dirt

3) There are fewer "reported" hospital visits because most vets now have their own portable X ray machines which they do right there in the stall...


bottom line... stats are generally skewed and this is no different...

talk to trainers, riders, vets... the consensus is synthetics have done more harm than good...

gm10, are there really any synthetic tracks that would be the equivalent to those dirt tracks where horses tend to find themselves towards the end of their careers? In many cases these horses are there for the sole purpose of squeezing any last bit of utility from them before they arrive at their final destination, often after a long career with many starts and unconscionable drug abuse as they bounce from one trainer to another. Being expected to perform over inconsistent surfaces laid over a base that hasn't been replaced or fortified for decades would only serve to expose the infirmaries/exploitations associated with a long racing career. The approach of limiting the data to only the better tracks would seem to me to be the only way to do this as the populations would be at comparable stages in their respective career cycles. This may not include 90% of N.A. races but without a synthetic surface laid over a base that is in shambles I can't think of another way to do it.

Being expected to perform over inconsistent surfaces laid over a base that hasn't been replaced or fortified for decades would only serve to expose the infirmaries/exploitations associated with a long racing career. The approach of limiting the data to only the better tracks would seem to me to be the only way to do this as the populations would be at comparable stages in their respective career cycles. This may not include 90% of N.A. races but without a synthetic surface laid over a base that is in shambles I can't think of another way to do it.

No there aren't, which is why I'm suggesting this approach. Feel free to map synthetic to equivalent dirt tracks.

Also, what if we restricted the data to 2-3-4 yo's? That would eliminate those older horses that you mention.

Au contraire. There a lot of cheap, weak horses. Not including them paints a false picture, as was clearly shown yesterday.

Why not throw in all cheap synthetic tracks? See post 127.

Excluding them might give you a true picture. If you have unsound horses, they are liable to break down no matter what surface. If you take samples of sound horses, you are likely to look only at breakdowns that are surface related, which all breakdowns clearly are not.

I wouldn't use Pen.
The inflated purses mask the very cheap crap they run over an old track.
What about Delaware, or Philly instead?

These are the numbers that I got from my DB. I filtered on the presence of the words "BROKE DOWN" in the chart comment.

Note that the breakdown rate does seem to tend to decrease very slightly with class for the ex-dirt tracks. That is definitely interesting. It doesn't apply for any of the other sets, however.

On your synthetic track data P4 has only 5 BD, where those either side have 10 and 20


How do you explain this GM10?? could it be because there are more runs, resulting in a higher chance of breakdown, just like there are with Dirt V Synth

There is a similar trend with the Dirt data i believe too.


Ok lets try this. Same car.

Which car do you think will suffer from more accidents and breakdowns??

Good point. Maybe we should come up with a more relative number, like a breakdown rate?

cj

Let's find a sensible solution to this.

CJ argues that the study is unreliable because there are no really bad synthetic tracks. Fair enough, that is worth investigating, but he is making the same mistake in his efforts by only looking at tracks that are among the best in the country. That is not where 90% of the races take place, and hence we can't extrapolate those conclusions (assuming there are any).

So I suggest that for each synthetic track, we try to find an equivalent on the dirt. This way we can hopefully settle on a set of tracks that are of comparable quality, and do the breakdown analysis on both groups.

I'll take a stab at it just to get things going, please add your suggestions if you have any and hopefully we'll come to a set of tracks that we can agree on.

Del Mar (average purse 47K) - Saratoga (average purse 72K)
Santa Anita (40K) - Belmont Park (49K)
Hollywood Park (34K) - Aqueduct (33K)
Golden Gate (14K) - Tampa Bay (14K)
Keeneland (51K) - Churchill Downs (71K)
Turfway Park (13K) - Finger Lakes (12K)
Arlington Park (23K) - Hawthorne (16K)
Presque Isle Downs (23K) - Penn National (19K)
Woodbine (50K) - Fairgrounds (30K)

How is that for everyone? Please suggest actual replacements.

I suggest using Canterbury and Fort Erie, how does that work for you?

The more I look at this, the more I'm seeing it is some tracks that are bad, not dirt as a whole.

Common sense says more games of Rugby i play more i'm going to get hurt. Multiply this by number of players and the injury rate will reflect it.

Yes they are because when i compare similar size datasets the difference seems minimal.

Well, those two are the closest tracks to Turfway in terms of purse value. I am breaking purse value down by surface since including turf skews the results.

Just to be up front, I know they have very few. Anyone can cherry pick tracks, that is my point. Some of your "comparisons" aren't even that close in terms of purse value.

You are using a strange jargon but I think I know what you mean. Funnily enough you seem to have noticed before CJ did. He's asking for FE/CBY to be added while the conclusion he wants is right in front of him.

Yes they are minimal. The evidence that poly is safer is not entirely overwhelming on the basis of this simple study. The only thing you can say is that they are safer than the dirt that they were replacing, but that may (or may not) have different reasons that the actual nature of dirt.

Of course it isn't, and that is what many have said all along. Obviously those tracks that were replaced are safer, they are brand new and the old ones were in bad shape. Only the most hardcore synthetic supporter would deny that is a factor.

By the way, Pinnacle is a very new dirt track. How does it compare to a Presque Isle Downs?

Don't give me the 'I told you all along' line.

Your first argument (there are more lower class dirt races, and lower class = more breakdowns), it is safe to say that one has been wiped off the table. There is simply no evidence for that.

The second one (older track base) hasn't been tested, but it sounds plausible. It has not been proven however. Other factors could play a major role too, such as climatic factors.

Anyway, my conclusion would be that

a) the synthetic tracks are safer than the dirt ones they replaced. The age of the track base is one possible explanation, but it has not been tested.

b) synthetic only seems marginally safer than dirt tracks of comparable class.

c) there is no relationship between class and breakdown rate. This arguments does not explain the results of the study.

Not entirely what I expected, and some things remain untested and unexplained, but that will be it for me, for now.

Here are the flaws I see when attempting to compare tracks:

1) Medications rules vary by state. Stricter rules may reduce breakdown rates, as I mentioned in a prior post. I have no evidence for this claim, but it seems worth considering.

2) It seems like CJ and GM10 are relying on the chart callers' descriptions to determine when a breakdown has occured. I'm not faulting either of them, but I suspect that approach is flawed. I suspect many horses that are listed as "pulled up/vanned off" were in reality euthanized. As a result, some tracks probably under report the term "breakdown" in their charts.

3) Slot subsidies skew purses, but I think someone already mentioned this and you've addressed it.

There is no doubt about this. I suspect "broke down" is only used when it is known for sure. "Vanned off" is probably safe to use as injured, but pulled up can be for tons of reasons.

Sure, they could be, but that would need to be really studied as well. Perceptions are not always reality. One thing I think that can be agreed upon is the initially posted study is way too simplistic to draw any real conclusions. Whoever is paying for it is wasting money.

This particular campaign supporting synthetics is coordinated and the timing is no coincidence.
