  Figure 3. Changes in skeletal muscle mass and body fat mass among weight-trajectory groups. SMM Skeletal muscle mass, FU follow-up. (A) Changes in skeletal muscle mass among weight-trajectory groups, (B) Changes in body fat mass among weight-trajectory groups. Values are least-squared means with 95% confidence intervals. The least-squared mean change in SMM (A) or body fat mass (B) levels was estimated for each weight-trajectory group at each follow-up time point using a mixed model assuming a random intercept with an unstructured structure. Estimates were obtained from a model that included the trajectory group, follow-up time point, sex, age, rural residence, educational level, physical activity (MET), current smoking, alcohol intake, body mass index, prevalent diabetes, prevalent hypertension, prevalent dyslipidemia, prevalent arthritis at baseline, height (the residual from a regression model in which height is the independent variable and SMM is the dependent variable at each follow up), mutually adjusted for body fat mass (in the SMM model) and SMM (in the body fat mass model) at each follow up, and the interaction between trajectory group and follow-up time point.
