Comparisons of Performance Measures Among the Four Prediction Models After 10-Fold Cross-Validation
| Model (Covariates Included) | Performance Measures |
||||
|---|---|---|---|---|---|
| Training Set C Statistic | Test Set C Statistic (10-Fold Validation) | Probability at Which Sensitivity and Specificity Are Maximized, % | Sensitivity | Specificity | |
| Female-only (age, BMI, snoring) | 0.84 | 0.84 | ≥ 7.0 | 0.82 | 0.70 |
| Male-only (age, BMI, snoring) | 0.81 | 0.81 | ≥ 15.7 | 0.78 | 0.70 |
| Sex × covariate interaction model (age, age × sex, BMI, BMI × sex, snoring ) | 0.84 | 0.84 | ≥ 11.3 | 0.79 | 0.73 |
| Non-sex-specific model (age, BMI, snoring, sex) | 0.83 | 0.83 | ≥ 12.0 | 0.77 | 0.75 |
