Lasix again

This is stuff that any statistics class goes over right after reading the syllabus.

We were told 90+% of horses bleed (I don't remember the exact number). I've taken enough statistics classes to know the results in the article would be enough to think that number is totally bogus. 15 out of 41 bled, not near the high percentage that was quoted. 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.

Completely random is a stretch. It isn't like it was 3 horses. What about the horses that bled through Lasix, 10 of 14. That random too?

I would like to know level "bled significantly" represents.

Horses bleed. Sometimes with lasix, sometimes without. Sometimes they race poorly and don't bleed. Sometimes they race well and do. Until a horse becomes a chronic bleeder it is almost always a random act. being that these were almost all lightly raced 2 year olds it is hard to imagine that there are too many chronic cases here.

I actually know what these things mean. I actually have seen the results of thousands scope reports. I have actual practical experience with racehorses, EIPH and lasix.

So just continue to disregard my posts, hell put them on ignore them if you'd prefer. Why understand the reality of a situation when you can be part of a "revolution" as I saw the anti-lasix cartel being described as on the internet this afternoon?

All I'm saying is that if 10 of 14 of the top horses still bled on Lasix, something is wrong. It isn't all wine and roses with Lasix. There are negatives, and the positives aren't as positive as many pretend.

And I'm saying that making any judgement based on the results of one race of Cal bred 2 yo's is insane. No one is saying that lasix is 100% effective or is some wonder drug. However unfortunately it is the best option that we have at this point.

If you want to take something negative out of the "study" consider that 45% of the horses scoped showed some signs of EIPH with or without lasix.

And I'm just saying if it is the best we have, it might not be worth having.

While I'm sure Lasix is far from the only reason the sport is in constant decline, I do think it is a reason. And a lot smarter people than me think so too.
