Optimal glucose-HbA1c ratio (GHR) cut-off values and performance of the cut-off values in predicting 1-year all-cause mortality in diabetic and non-diabetic ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction patients
| STEMI | NSTEMI | |||
|---|---|---|---|---|
| Diabetic | Non-diabetic | Diabetic | Non-diabetic | |
| Statistical optimal GHR cut-off in mmol/L | 2.11 | 1.72 | 2.10 | 1.43 |

| Positive predictive value in % (95% CI) | 22.0 (18.6–25.4) | 18.5 (15.4–21.6) | 11.7 (8.5–14.9) | 5.8 (3.5–8.1) |
| Negative predictive value in % (95% CI) | 94.4 (93.5–95.4) | 96.2 (95.5–97.0) | 94.1 (93.0–95.1) | 97.6 (96.8–98.4) |
