Heatmap of mean frailty score in quartiles of serum BCAAs stratified by gender and LTL in the oldest-old subjects. The darker the color, the higher the frailty score and the worse the health status. BCAAs, branched-chain amino acids; Val, valine; Leu, leucine; Ile, isoleucine; LTL, leukocyte telomere length.
