INS and type 2 diabetes mellitus: In our multivariate analysis, higher BMI (OR 1.19; p = 0.002), lower preoperative insulin use (OR 0.8; p = 0.001), and lower HbA1c (OR 0.29; p < 0.001) at baseline were associated with long-term T2D remission (n = 16) (Table S4), which is in line with previous data [16].
