First, it’s not “Post Hoc” and saying that is incredible misinformation. You can’t simply say things like that so matter of factly, it’s irresponsible. Of course the last 4 years have made this type of thing common place in the culture. Secondly, there are not enough people in the placebo arm to ever get enough power for OS so the separation is not a “failure” it’s a result of changing understanding of immune therapies and how they work. If you feel throwing the baby out with the bath water is such fundamental and unchangeable dogma then you’re nothing more than one of the many staunch regressive thinkers over the centuries who choose to refuse acknowledgment of transitional science; the same people who persecuted Socrates, Jesus, Rhazes, Servetus, Galileo, and Einstein to name a few. Many fight to the end for such dogma as to make their efforts in retrospect appear illogical, defensive, and mean spirited at best.
