>If an intervention is shown to be effective in treating COVID-19, the design allows the replacement of the placebo group with the effective intervention.<p>Is't that kind of bad?<p>Say, if by pure chance, there is an intervention that is equally effective as Ivermectin, wouldn't it cause the whole thing to zero out, or show very little benefit for the Ivermectin?<p>EDIT:<p>They also say..<p>> It would not take much of a clinical trial to know whether that was true or not, and almost every physician would be able to spot really quickly whether there was a drug that miraculously was helping people. But we’re not getting that feedback from physicians<p>Isn't that the exact kind of feedback that is being neglected right now?
