Correlation between the 24-month-percentage of total weight loss (%TWL) and each variable. (a) The zero-month skeletal muscle mass (SMM) exhibited a positive correlation with the %TWL at 24 months (rs = 0.46, p = 0.007). (b) The zero-month skeletal muscle index (SMI) was positively correlated with the %TWL at 24 months (rs = 0.41, p = 0.017). (c) The 12-month percent body fat (%BF) was negatively correlated with the %TWL at 24 months (rs = −0.61, p < 0.001). (d) The 12-month skeletal muscle mass (SMP) exhibited a positive correlation with the %TWL at 24 months (rs = 0.61, p < 0.001). (e) The 12-month SMM to FM ratio (SMM/FM) was positively correlated with the %TWL at 24 months (rs = 0.61, p < 0.001).
