ESR was correlated with the expression of FOXO3A in the sarcopenia patients group (r=0.69, p=0.004) (Figure 4C), geriatric control group (r=0.41, p=0.042) (Supplementary Figure S3D), and when analyzing all hospitalized groups together (r=0.38, p<0.001)(Supplementary Figure S3E). Here, FOXO3 is linked to sarcopenia.
