  1. ASMI: appendicular skeletal muscle mass index; Sarcopenia: the presence of low muscle mass plus the presence of either low muscle strength or low physical performance; Continuous data was summarized as mean ± SD, categorical data variables were reported as numbers (percentage). Student’s t-test and Pearson’s chi-square test were performed to test the difference/associations between males and females. Student’s t-test was used on categorical data and Pearson’s chi-squared test was used on continuous data
