Figure 1

Five-year incidence of diabetes by tertiles of SI and AIR. Results were adjusted for age, sex, ethnicity, center, IGT, family history of diabetes, and BMI. Cut points for tertiles of SI (× 10−4 minute per microunit per milliliter): lower, ≤1.16; middle, 1.17–2.38; and upper, ≥2.39 (Ptrend < 0.001). Cut points for tertiles of AIR (microunits per milliliter): lower, ≤37.5; middle, 38.0–75.0; and upper, ≥75.5 (Ptrend < 0.001). Numerators and denominators for each cell are number of participants who converted to diabetes and total number of participants at risk, respectively.
