Time courses of BMI, %TWL, and HbA1c from the first visit to 5 years after LSG for all included subjects who underwent LSG (n = 210) (Fig. a–c) and changes in ΔBMI, %TWL, and HbA1c in remission-maintained and relapse groups (Fig. d–f). Data are presented as means ± SD. *p < 0.05 versus 1st visit. Repeated measures ANOVA followed by Bonferroni multiple comparison test was used to evaluate the overall change (main effect p value) and differences between the two groups (interaction effect p value). LSG, laparoscopic sleeve gastrectomy; BMI, body mass index; %TWL, percentage total weight loss; po, postoperation.
