The answer is political, not technical.

We use Stata for clinical trials, but we are in the academic sphere, and not beholden to the FDA. FDA requires that SAS format be used for reporting, which gives them an edge. It is also one of the reasons that Stata has FDAsave as an export option. It's also why all the drug companies want SAS programmers and nothing else.

I personally use Stata to analyse clinical trial data, and to do the
power calculations beforehand. However, as you say, most of the
mainstream corporate clinical trials sector uses SAS. A lot of the
reason for this seems to be inertia, including the perception that
regulators will be frightened by a clinical trial report produced using
anything other than SAS. I don't think there is much that Stata can't do
that SAS can in that field, xcept to have the look and feel of SAS.

Subject: st: clinical trials


Does anyone on the list use Stata for clinical trials analysis? I get the impression companies that specialize in this field use SAS almost exclusively. From what I know of Stata's feature set, I don't think this is because Stata cannot be use to perform analysis of clinical trials data. SAS certainly pushes this area of use with SAS, and they have several SAS published how-to texts.
