>>It prevents deaths - just not more than 30% of the expected CABG deaths at 30 days. <<

Better said: It prevents deaths or MIs - just not....

It could indeed reduce death at a much greater rate than 30%, since death/MI have same formulaic value = 1, and such a finding might also be significant. We don't know since they did not mention even one p value or one individual secondary endpoint.

Anyone, please comment on how statistician would discredit the fact that the larger group, the one that is more highly powered and more accurately reflects clinical practice, achieved the composite at 30 days with statistical significance? Is that (insert sneer here) some kind of subset?

When you are talking about saving lives and heart tissue, who cares if the company first thought, based on previous 37 pt valve group, there was no benefit to be found in valve pts?
