The one area that does interest me though is why would the DMSC committee add the 75% review unless they felt that there was some event happening at that timeframe? If we were meeting or just below p < .05 then the normal recommendation would be to let the trial finish. At 75% we would just be over p <.05 and no other action would be necessary for the DMSC other than to say continue. There has to be some significant event that could happen at 75% or it doesn't make sense to stop it so soon and risk interrupting the trial again.
…Sorry for more fact-less reading of the tea leaves
