NPV = (number of true-negatives/[number of true-negatives + number of false-negatives]). Accuracy score: (Sensitivity + specificity + PPV + NPV) × 100. Comprehensive score: Number of monograph ...

With this classification, the sensitivity of repeated MMSE for detecting dementia was 68%, and the specificity was 70% (PPV, 42%; NPV, 88%). With a score of ≤24 on the MMSE as the absolute ...

Diagnostic accuracy of the screening tools versus the reference method was expressed as sensitivity (Se), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV).
