Dunno about that. Was looking for an Oxford U clinical trial of some potential inexpensive treatment for Covid-19 that started ~16 months ago. Given any such treatments are only for few days and only effective very early in course of infection, one would expect to have published results by now, whatever the outcome. But so far nothing to date. Maybe they hit the common patient recruitment bottleneck and don't have a statistically valid sample size? Point is it's often hard to predict how long it will take to have data worth publishing.
