Can there be a [PREPRINT] flag or the like added to titles for posts like these on HN? It's really important to keep in mind that preprints are not peer reviewed, and with the increase in interest in healthcare papers on this forum, it would be really helpful to be able to make that clear. It's more likely that the march 2019 sample is a false positive, not a true finding, and in peer review the statistical validity of that finding would be called into question and further validation would be required. Just posting the headline makes it seem as if this is something that has been conclusively determined without the disclaimer that medrxiv itself puts at the top of each of these publications: that preprints aren't peer reviewed and should not be used to inform clinical decisions etc.
