OR odd ratio, US United States, RYGB Roux-en-Y gastric bypass, AIC Akaike information criterion
*The following variables has P values of >0.10: age, sex, years since diagnosis of T2DM, BMI, waist, weight change from baseline to 24 months, HbA1c, SBP, DBP, LDL-C, HDL-C, triglycerides, total cholesterol, on non-insulin antidiabetic meds, on statins, on non-statin lipid-lowering meds, on BP meds, number of meds for control of glycemia, dyslipidemia, and BP
#Predictors in univariate analysis with P value <0.10 (except for fasting C-peptide since it is highly correlated with stimulated C-peptide) were included. Smaller AIC values are better.
