Associations between appendicular lean mass index, handgrip strength, and physical performance. This model was constructed based on the hypothesis that ALMI predicts handgrip strength and that handgrip strength predicts physical performance. Physical performance score is not adjusted for body mass index as fat mass was included in the model. Values along the arrows are expressed as standardized beta coefficient and R ² (in bold) not adjusted for covariates (model 1, in blue) and adjusted for fat mass and age (model 2, in black). ^* P value <0.001; ^‡ P value <0.05. ALMI, appendicular lean mass index.
