Performance comparisons of RSF and multivariate COX models to predict VT/VF (both with fivefold cross-validation approach and significant univariate predictors as model input)
| Model | Precision | Recall | Brier score | Harrell’s C index |
| RSF | 0.95 | 0.93 | 0.09 | 0.91 |
| Multivariate cox | 0.86 | 0.84 | 0.13 | 0.82 |
RSF, random survival forest; VT/VF, ventricular tachycardia/ventricular fibrillation.
