To exclude the possibility that the number of deaths caused by COVID‐19 was simply increased according to an increase of confirmed cases of COVID‐19 regardless of HLA genotypes, we next performed ANCOVA and adjusted the number of confirmed cases of COVID‐19 between HLA‐A*02:01 and non‐HLA‐A*02:01 groups. The gene discussed is HLA-A; the disease is COVID-19.
