Lasix again

That would be statistically significant given the base of 90+% that has been cited. In other words, if horses really bled at such a high rate, the odds of finding a sample of 41 where only 36% match the criteria are basically nil.

And 10 out of 14 WITH Lasix bled? Yeah, that doesn't sound too effective to me. And we are talking the best (and best cared for) horses.

90% bleed at some point, not necessarily on Breeders Cup weekend. If 90% of horses bled every race there would be no racing. You see what people don't seem to understand is that we don't have any idea of when it will happen.

The fact that 45% of them showed some sign of EIPH was surprisingly high to me considering these are lightly raced, young horses in a good weather environment.

Of course I realize that the numbers here are completely random and nothing can really be gleaned from them with any degree of accuracy.
