So as for the study from China, it's a worse example. This was a study that was published by the Journal of Beijing University in China, and the conclusion it reached was that hydroxychloroquine was as effective as no treatment. It too was a really small study of only 30 patients. 15 were given the drug, and after a week, 13 tested negative. Of the 15 who weren't given the drug, 14 tested negative after a week. The conclusion in the paper was deemed not statistically significant, and further studies were required to determine if there was any real benefit there.
