Cox proportional hazard model for the association of postoperative weight parameters with diabetes relapse at 5 years after LSG. HR, hazard ratio; %TWL, percentage total weight loss; %WR, percent age weight regain; CI, confidence interval. HRs were adjusted for age and gender. Percentage WR was calculated using the following formula: (current weight − nadir weight)/(presurgery weight − nadir weight) × 100. *p < 0.05. %TWL was calculated using the weight at 1 year after LSG, and %WR was calculated using the change from nadir weight after LSG to the most recent weight.
