Foundational Statistical Principles in Medical Research: Sensitivity, Specificity, Positive Predictive Value, and Negative Predictive Value [PDF]
Medicina, 2021 Sensitivity, which denotes the proportion of subjects correctly given a positive assignment out of all subjects who are actually positive for the outcome, indicates how well a test can classify subjects who truly have the outcome of interest. Specificity, which denotes the proportion of subjects correctly given a negative assignment out of all subjects

COVID-19 Thrombosis: Understanding the Negative Predictive Value in a Pandemic [PDF]
Blood, 2020 A test's negative predictive value-the probability that a negative result is a true negative result-is dependent on the prevalence of the condition. The present pandemic circumstances present us with unique challenges. False negatives in current testing methodology are to be expected.[1] Thus, a rigorous and contextual interpretation of a negative test

Error in the Calculation of the Correct Use of Positive and Negative Predictive Values [PDF]
Journal of Ultrasound in Medicine, 2008 lished in the November 2004 issue, there is a mistake in the calculation of the positive predictive value (PPV) and negative predictive value (NPV) for the reported study. On page 1460, the authors reported that “Calcifications were seen in 2 (5.6%) of 36 benign nodules and 12 (35.3%) of 34 malignant nodules in this study.

The predictive receiver operating characteristic curve for the joint assessment of the positive and negative predictive values [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008 Binary test outcomes typically result from dichotomizing a continuous test variable, observable or latent. The effect of the threshold for test positivity on test sensitivity and specificity has been studied extensively in receiver operating characteristic (ROC) analysis. However, considerably less attention has been given to the study of the effect of
