Excluded individuals consisted of study subjects with at least one functional measure (grip strength, sit-to-stand, 6 minute walk, URICA, WEL-SF, PROMIS) missing in their data. All values presented are mean ± standard deviation, or counts (percent). A P value represents the differences between individuals with and without ALM-defined sarcopenia (<19.75 kg in men; <15.02 kg in women).
