Don’t you have to juxtapose that with the abo % in the population? According to Wikipedia(only showing +, avg, https://en.m.wikipedia.org/wiki/Blood_type_distribution_by_c...) that’s: O:38.67% A:27.42% B:22.02% AB:5.88%

edit: added wikipedia link

They did have a control group from the healthy population of Wuhan which had those at...

"ABO group in 3694 normal people in Wuhan showed a distribution of 32.16%, 24.90%, 9.10% and 33.84% for A, B, AB and O, respectively"

I’d be happy to change the title, though it is basically quoted from the article conclusion.

Not peer reviewed, but an interesting observation nevertheless. There will be more data soon.

Given the fact SARS had a similar profile, this should be a reasonable assumption.

I’m not saying it’s at the same standard as being peer reviewed, though it’s more likely than not that the conclusions from this data will remain true based on both the data and the correlation.

For future reference, Hacker News guidelines call for using the article's original title as the title of the submission. https://news.ycombinator.com/newsguidelines.html (the moderators seem to have fixed this for you)

Thanks for posting this. Would others agree here that this is a very weak correlation of blood type to Coronavirus severity?

I would like a hypothesis tested on individual alleles as I outlined in another comment: it's not that weak correlation if looked at that way, especially since eg. A* groups are present in Caucasian population in ~45% compared to ~35% in Asian population (numbers pulled from another site cited in that other comment of mine).
