Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) with 95% confidence intervals of the EEG-based present performance model after grouping the observed and estimated F-Measure into classes of unacceptable (F-Measure < 0.80) and acceptable (F-Measure ≥ 0.80) performance.
