1
Based on definitions identified/discussed in Johnson Stoklossa et al. (8). ADL, activity of daily living; ASM, appendicular skeletal mass; FMM, fat-free mass: FM, fat mass.
2
Self-reported difficulty with ADLs available for n = 111.
3
Spearman's r reported for men due to small sample size (n < 30).
