  1. BCAA, branched-chain amino acids; Val, valine; Leu, leucine; Ile, isoleucine; LTL, leukocyte telomere length; 95%CI: 95% confidence interval. #β represents the difference in frailty score between each subgroup and the reference group. P interaction was estimated from the general linear model by converting BCAAs and LTL into binary variables with a median split method.
