Incidence of type 2 diabetes in subjects with NGT divided into three groups based on FPG
| FPG (mg/dl) | 1-h PG (mg/dl) | n (% of SAHS participants) | FPG (mg/dl) | 1-h PG (mg/dl) | 2-h PG (mg/dl) | OR (95% CI) |
|---|---|---|---|---|---|---|
| <90 | <125 | 894 (72) | 81 ± 1 | 95 ± 26 | 87 ± 11 | 1 |
| 125–150 | 286 (73) | 82 ± 6 | 135 ± 10 | 100 ± 22 | 4.7 (2.0–11.1) | |
| >150 | 219 (72) | 83 ± 6 | 175 ± 19 | 109 ± 21 | 7.4 (3.3–17.1) | |
| 90–100 | <125 | 489 (29) | 95 ± 3 | 99 ± 14 | 94 ± 18 | 1.8 (0.6–5.2) |
| 125–150 | 255 (30) | 95 ± 3 | 136 ± 10 | 105 ± 19 | 2.7 (1.1–6.9) | |
| >150 | 265 (34) | 96 ± 3 | 180 ± 18 | 111 ± 20 | 11.3 (5.0–25.8) | |
| >100 | <125 | 329 (7) | 106 ± 5 | 102 ± 12 | 101 ± 17 | 1.7 (0.4–6.7) |
| 125–150 | 277 (9) | 107 ± 5 | 137 ± 10 | 108 ± 19 | 4.0 (1.3–12.5) | |
| >150 | 432 (10) | 109 ± 6 | 188 ± 27 | 114 ± 18 | 17.7 (7.5–41.9) |
Data are means ± SD unless indicated otherwise. Subjects with NGT were divided into three groups based on FPG <90, 90–100, and >100 mg/dl. Subjects in each group were further subdivided based on a 1-h plasma glucose (PG) concentration <125, 125–155, and >155 mg/dl. Age, BMI, ethnicity, and systolic blood pressure were included as covariates in the model.
