An easy way to understand PPV is to dissect the name. In Positive Predictive Value, we are looking at how good a positive test is at predicting that a person actually has a disease. Positive predictive value refers to the percentage of patients with a po
However, this requires a good estimate of the questionnaire's positive predictive value, which may vary among populations. This study attempts to provide a more accurate estimate of the positive predictive value of health history questionnaires regarding varicella and rubella disease and vaccination ...
We identify 74 statistically significant gene–disease associations across 27 genes. Seven of these conditions have a positive predictive value (PPV) of at least 30% in both cohorts. Three are already used in population screening programs (BRCA1,BRCA2,LDLR), and we also identify four new candid...

The performance appraisal of this method is validated by computing various performance metrics, like true positive predictive value (PPV), negative predictive value (NPV), false discovery rate (FDR), Matthews’s correlation coefficient (MCC) other than accuracy (ACC), sensitivity, and specificity. ...
A combination of estrogen receptor-negative status and HSD17B4 methylation showed a positive predictive value of 80.0%. During HER2-directed neoadjuvant therapy, HSD17B4 methylation was the most reliable marker to monitor response to the therapy. These results showed that HSD17B4 methylation is a ...
The highest AUC, with a good predictive value, was found for IL-10 > 39.87 pg/ml in separating EBER-positive lymphoma-associated hemophagocytic lymphohistiocytosis from non-neoplastic EBV-associated hemophagocytic lymphohistiocytosis. The diagnosis of EBER-positive lymphoma-associated hemophagocytic ...
MAST calculates the positive predictive value (PPV), negative predictive value (NPV), sensitivity (TPR), and specificity (SPC). For convention below, TP = true positive, TN = true negative, FP = false positive, FN = false negative. The sensitivity is the probability of the algorithm ...
The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for the detection of CIN3 + were determined with Wald 95% confidence intervals (95%CI) for the following triage strategies: methylation analysis, HPV16/18 genotyping, HPV16/18 genotyping combined...
