Odds ratio = 12.7 (P < 0.001) |

Negative predictive value = 54.5% |
- Sensitivity is the percentage of subsequent responders (HbA1c <7% or ≥ 1% reduction) correctly identified (true-positive rate). Specificity is the percentage of subsequent nonresponders (HbA1c ≥7% and < 1% reduction) correctly identified (true-negative rate). Positive predictive value is the percentage of subsequent responders among early responders. Negative predictive value is the percentage of subsequent nonresponders among early nonresponders. Abbreviation: HbA1c glycated hemoglobin
