Diabetes incidence according to (A) oral glucose tolerance test groups (Normal: solid gray line with squares; IFG: dashed black line; IGT: solid black line); Log-Rank; P = 0.005 for normal vs. IFG and IGT; and (B) to the combination of Metabolic Syndrome presence and glucose status; Chi-squared; MetS present: P = 0.018 for normal and IFG vs. IGT and MetS absent: P = 0.045 for normal vs. IFG and IGT. IFG = impaired fasting glucose, IGT = impaired glucose tolerance.
