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 ...

Compared with the unadjusted cerebrospinal fluid WBC count, the adjusted one had similar sensitivity, PPV and NPV for bacterial meningitis. NPV and PPV of adjusted CSF WBC count were 100% and 14.2%, ...

To compare the ability of VAN and RACE to detect LVO, we calculated their sensitivity, specificity, positive and negative predictive values (PPV, NPV) and area under the ROC curve (AUC). Results In ...
