There were three additional HLA types associated with the EWGSOP’s combined definition of sarcopenia in the female-only analysis (HLA-B*15:01 OR 1.089, 95% CI 1.03–1.15, p = 3.27*10–3; HLA-DRB1*04:04 OR 1.107, 95% CI 1.03–1.19, p = 3.65*10–3; and HLA-DQB1*03:02 OR 1.07, 95% CI 1.02–1.12, p = 3.2*10–3), which were not identified in the analysis including both sexes (FDR-adjusted p > .05). Here, HLA-B is linked to sarcopenia.
