Note that there are limited primary evidence regarding the association between blood groups and COVID19 infection, upcoming relevant studies will be added to the results of the present meta-analysis. Of the evidence included in this meta-analysis, five studies had reported the frequency of blood group AB among COVID-19 infected people varied between 3.08% and 13.68%. Combining the results of this two evidence, applying random effect model (I-square=0%, Q=0.41, P=0.522), the odd ratio for death among COVID-19 infected people having blood group A was estimated as 1.12 (95% CI: 0.87, 1.45). Meta-analysis of studies showed no significant association between mortality and different blood groups in COVID-19 patients.	./cache/cord-262716-hea84shy.txt	./txt/cord-262716-hea84shy.txt
