Fig. 1 Differences between sexes in longitudinal changes from baseline in body composition, fat mass (kg) (A), fat-free mass (kg) (B), and muscle mass (kg) (C) in adolescents after LRYGB and within-sex differences in absolute body composition at 5 years compared with adolescent controls on nonsurgical treatment. Mean ± SEM. Solid black lines denote mean group measurements in boys after LRYGB, and solid gray lines denote mean group measurements in girls after LRYGB. Symbols o and x denote mean group measurements in control boys (o) and control girls (x). *P < .05, **P < .01, ***P < .001, +changes from baseline, #within-sex difference. LRYGB = laparoscopic Roux-en-Y gastric bypass; SEM = standard error of the mean.
