I am absolutely astounded that you consider academic studies in a more
critical light than industry driven studies. Shouldn't all studies be taken
on their merit - or are you suggesting that academic studies are naturally
flawed in some way?
> Did excluding these 4 subjects alter the results of the trial?
Simply the patients were removed before analysis. They did not meet
protocol requirements (e.g. some received unfractionated heparin).
It is my best belief that if we continued to recruit patients that we would
see the same signal as the trial found. The trial was adequately powered so
we are not expecting bias inherent in underpowered studies (compare to the
underpowered APPROVe study wrt CVS observations).
In addition, the purpose of this part of the thread, for me, was to show
that a) studies do arise in academic settings that improve patient care [to
respond to Mark's comments] and b) that simplifying the dosing on the drug
label to make the drug "easier to use" doesn't necessarily result in better
patient outcomes.
