This is a preprint. This sentence could be modified and not change the core claim of the paper. What's interesting is studying the data on which this is based (some commenters yesterday said it made a few mistakes https://news.ycombinator.com/item?id=22935451 https://news.ycombinator.com/item?id=22935451 ; but without enough details to dismiss the paper entirely), and the other papers (this is not the first) which have similar claims. The doctors are rushing to share their core (incomplete) data to have others study it. In normal times, this type of study would stay hidden for months (I've heard up to two years for some niche domains) so that everything could be checked, re-checked, and editors could fix the introduction mistakes. We aren't in normal times.
