Positive correlation between fat-free mass and handgrip strength for both arms.

(A) Positive correlation between muscle mass (kg) and right-arm handgrip strength (kg) (Spearman’s Rho = 0.813, p<0.001). (B) Similar correlation for the left arm (Spearman’s Rho = 0.798, p<0.001), emphasizing the link between fat-free mass and handgrip strength.
