Statistically Significant
With two years of data in the Equine Injury Database, the Jockey Club is out today with updated fatality rates. The overall rate declined to 2.0 per 1000 starts from the 2.04 reported earlier this year. By surface, the rates are 2.14 on dirt (unchanged), 1.74 on turf, and 1.55 on synthetics (down from 1.78):
Parkin noted that the change in the overall fatality rate stemmed from cumulative two-year data that revealed a statistically significant difference in the prevalence of fatality on both turf and synthetic surfaces versus dirt. The difference in the prevalence of fatality between synthetic and turf surfaces was not statistically significant.
Confirms the impression that synthetic surfaces are safer (although the usual caveats apply re: uncertainty of factors such as new track bases, improved vet checks, anecdotal reports of increased non-fatal hind injuries, etc.).
12:55 PM Update: More from Thoroughbred Times: “… horses racing on a synthetic surface were 27.6% less likely to break down …“
