BRD2 and sarcopenia: There were no significant associations observed between FSH and sarcopenia (OR 0.511, 95% CI 0.178–1.467, P = 0.212) or severe sarcopenia (OR 0.400, 95% CI 0.136–1.175, P = 0.096) after controlling above confounders, although the prevalence of sarcopenia was significant different between two groups (P < 0.05).
