despite the various sources pumping hydroxycholorquine, one has to leave open the possibility that placebo may see very similar results as the control arm. that's what they're trying to determine. has anyone noticed some say it works great and others say it did nothing? many, many people are recovering without any treatment. it's not far fetched to assume someone on HC would have recovered without it.
we just won't know the answer until we see results of a large, controlled study w/ a big placebo arm. the interesting subset of data i'll want to see is what happens to the placebo patients that are switched to HC. that will be very interesting.
