Partial correlation: adjusted for age.

Bold: p<0.05.

* is significantly greater in absolute value than the correlation coefficient between SMI and the same physical function in a test of difference of correlations (p<0.05).

Abbreviations: CSA, cross-sectional area; BMI, body mass index; ASM, appendicular skeletal muscle mass; SMI, skeletal muscle mass index; CTV, computed tomography attenuation value; KES, knee extension strength.
