Prevalence of IFG, IGT and T2D newly diagnosed by ADA recommendations
| NGT | IGT | T2D | |
| 2hPG | 397 (75%) | 98 (18%) | 34 (6%) |
| FPG | 437 (82%) | 88 (17%) | 6 (1%) |
| HbA1c | 150 (28%) | 324 (61%) | 57 (11%) |
HbA1c was able to detect IGT and newly diagnosed T2D with a major percentage than 2hPG and FPG. Conversely, 2hPG and FPG were able to identify more subjects with normoglycemia than HbA1c.
