No one is saying ignore them. The problem is you have a big ascertainment / publishing bias. How many people had absolutely no benefit from ivermectin but did not come to TexAgs to say it? How many people had the same reaction but the other way (ivermectin folks did slightly worse)? How large was the placebo effect of taking a defined protocol of recommended meds from a trusted doc vs fluids and dayquil?
We don't know. The only way you know is by doing clinical trials.
