Some quick points:
- Reported odds ratios[0] of 1.2 for A and 0.67 for O.
- This is a preprint, so it has not been peer reviewed.
- They compared blood type of patients with that of the general population in the region.
- Data is from 2,173 patients at three hospitals. The data varied between them, but Wuhan had the overwhelming majority (1,775, or 81%) of cases.
- Since these are all patients, they presumably are weighted toward the more extreme responses. There were minimal age and gender differences, though.
- A similar response for type O was apparently reported for SARS.

- graeme 7y agoDid they list an odds ratio for having a severe/critical case?
- Amorymeltzer 7y agoNo, they didn't look at severity. They did report ABO distributions for 206 deaths in Wuhan, which could be considered a proxy for severity but likely has a lot of confounding variables, such age, wealth, etc. Those data were in-line with the top-line results, but that's a small sample.
- usrusr 7y agoThey are looking at data from hospitals, so I'd expect mild cases to be excluded. Semantic nuances seem to be very relevant to the applicability (or not) of this selection to the exact wording of the result: is a SARS-CoV-2 infection that remains harmless because it is overcome before spreading from throat to lungs classified as a light case of Covid-19 or is that label reserved for more serious forms of infection?
- gnramires 7y agoIf ABO type is independent from age/wealth/etc., then those variables don't need to be controlled (although I guess that should indeed be investigated/confirmed first).
