There is. A team of Chinese doctors and South Korean doctors published before anyone else. There have been other American doctors who have reported good results, but they are ignored by the mainsteram media. Research that back up these findings started as far back as 2015. The evidence is there, but it is deliberately being ignored.
That makes sense. When something is the consensus, every little fact that seems to support it get vacuumed up and amplified. But when it’s not, each individual is pushing on string.
It would be great if someone could systematically collect all the cases including the ones you cite.
