Predictors of regression from prediabetes to normal glucose tolerance at the 3-year follow-up. ORs (95% CI): odds ratios and 95% confidence intervals calculated in the multivariate logistic model. Variables in the model: sex, age, family history of diabetes, smoking, drinking, physical inactive, SBP, BMI, TC, TG, and categories of Pre-DM. Family history of diabetes, smoking, drinking, and physical inactivity were not significantly associated with the regression from pre-DM to NGT and were not shown in the figure. SBP: systolic blood pressure; BMI: body mass index; TC: total cholesterol; TG: triglyceride; Pre-DM: prediabetes; IFG-IGT: combined status of IFG and IGT; i-IFG: isolated impaired fasting glucose; i-IGT: isolated impaired glucose tolerance.
