Table 1 Metrics of the confusion matrices derived from each of the fast ripple (FR) resection measures at Youden’s J of the respective receiver operating charecteristic (ROC) curves for predicting post-operative seizure free outcome (top) and improvement in seizures (bottom). Brackets indicate the 95% confidence interval. For the patients without FR mutual information (MI) networks, (i.e., indeterminate) confusion matrices values were imputed appropriately (see supplementary methods).
