OrechDin, this journal is not high there, but it is a valid academic publication, and gofundme should be OK for the current emergency. this is not a time for writing NIH proposals. I see above that an underlying study was a fraud, that’s an issue.
Also, they have maybe 10 different questions and only one of them (an important one, though) has moderate confidence, all the rest are low confidence. if you look at overall multi-test statistics – a chance to have one moderate out of 10 tests – would indicate low confidence inthe overall result. It is as if you throw dice 10 times, then select the highest value out of 10 and say that your “average” is 10 out of 12.
that said, it is a valid strategy to search through existing medicines to see if any of them would help. The benefit is that safety is already known and manufacturing exists. So, if there is a way to improve outcome even by a small number (as these tests seem to indicate), it is worth trying.
There may be some hidden correlations that help in some cases. For example, it is possible that extra vitamins are very helpful in places with deficiency of that vitamin, but less in others
