Any statistical details on that blood type study?

The research article is here.

The  ABO  blood  group  in  3,694  normal  people  in  Wuhan  displayed  a  percentage  distribution of 32.16%, 24.90%, 9.10% and 33.84% for A, B, AB and O, respectively, while  the  1,775  patients  with  COVID-19  from  Wuhan  Jinyintan  Hospital  showed  an  ABO  distribution  of  37.75%,  26.42%,  10.03%  and  25.80%  for  A,  B,  AB  and  O,  respectively

The ABO blood group in 23368 normal people in Shenzhen displayed a percentage distribution of 28.77%, 25.14%, 7.32% and 38.77% for A, B, AB and O, respectively. Analysis of 285 patients with COVID-19 from Shenzhen showed proportions of blood groups  A,  B,  AB  and  O  to  be  28.77%,  29.12%,  13.68%  and  28.42%,  respectively.

They also looked at the separate age groups and found that the risks were generally the same across each. (So this isn't the case that more old people had A and more young people had O.)
