Progression to prediabetes and type 2 diabetes. (A) Risk factors for the progression to type 2 diabetes at the 10-year follow-up examination in participants with normal glucose tolerance (NGT) or prediabetes (n = 571). (B) Risk factors for the progression to prediabetes at the 10-year follow-up examination in participants with NGT (n = 241). (C) Risk factors for the progression to type 2 diabetes at the 10-year follow-up examination in participants with NGT (n = 241). D: Risk factors for the progression to type 2 diabetes at the 10-year follow-up examination in participants with prediabetes (n = 330). Multinomial logistic regression model was used after adjustment for age, sex, waist circumference, systolic blood pressure, and concentrations of fasting plasma glucose, alanine aminotransferase, and C-reactive protein. The levels of cytokines are expressed as tertiles, and odds ratios (95% CIs) are shown above the black circle.
