I already acknowledged the 3month/6 month thing, and that I was using clinicaltrials.gov, which still shows 3. But that doesn't answer my fundamental argument, which is that the numbers do not allow for strict chronological enrollment of method A before B (the lack of gaps in the waterfall during the slow enrollment period).-dwiggd

Yes they do, and this is what you are all missing.

9 of the 11 that died were all Method A. Almost all of the patients that died were enrolled under inferior criteria (mostly 2-6 months OS is obviously not the "> 6 months/ 500 mm3 lymph count" crit). Therefore the Method A "cohort" survival rates were negatively impacted by the weaker initial criteria. When combined with the obvious long tail survivors that were enrolled first and given Method A (see student abstract), that de facto means most or all Method B were enrolled later, and so most fall under the superior crit.

That confounds any comparison.
