Comparison of ROC curves for different surrogates to predict insulin resistance and infertility
| Objects/Surrogates | Cutoff (Sensitivity, Specificity) | AUC (95% CI) | P-value |
|---|---|---|---|
| Insulin resistance | |||
| TyG index | 8.12 (0.63, 0.70) | 0.71 (0.68, 0.74) | < 0.0001 |
| TyG-BMI index | 226.48 (0.74, 0.81) | 0.83 (0.80, 0.85) | |
| Infertility | |||
| HOMA-IR index | 2.34 (0.69, 0.57) | 0.65 (0.60, 0.71) | > 0.05 |
| TyG index | 8.19 (0.62, 0.60) | 0.62 (0.57, 0.68) | |
| TyG-BMI index | 242.18 (0.68, 0.64) | 0.68 (0.62, 0.74) |
AUC, area under the curve; CI, confidence interval
Z-test was used to compare tatistically significant differences between AUCs
