  1. Sensitivity, specificity and predictive values with LM as the Gold Standard are shown for ledFM and uvFM The PPV (positive predictive value) and NPV (negative predictive value) concern the study population and the corrected values used the prevalence of patients at Albert-Schweitzer Hospital with history of fever [8].
