Negative predictive value of the Duke criteria for infective endocarditis

The American Journal of Cardiology, 1996
With use of new Duke criteria, 405 episodes of suspected endocarditis were previously classified as "definite," "possible," or "rejected" endocarditis. To determine the negative predictive value of the Duke clinical criteria for the classification of suspected endocarditis, chart review and follow-up were performed for the 52 episodes in which the ...

Using Negative Predictive Values

Pediatrics, 2006
To the Editor .— In “Poor Predictive Validity of the Bayley Scales of Infant Development for Cognitive Function of Extremely Low Birth Weight Children at School Age,”1,2 we learn that things have not changed in the last 40 years. Early mental tests are still poor predictors of later intelligence,3 and normality at early ages is a better predictor of ...

Binary regression: Total gain in positive and negative predictive values

Biometrical Journal, 2012
Models that predict disease incidence or disease recurrence are attractive for clinicians as well as for patients. The usefulness of a risk prediction model is linked to the two questions whether the observed outcome is confirmed by the prediction and whether the risk prediction is accurate in predicting the future outcome, respectively.

Test Accuracy As Positive and Negative Predictive Values

2022
Abstract This chapter explains how to generate positive and negative predictive values from the rows of a 2×2 table and that unlike sensitivity and specificity, they answer patient-relevant questions such as the probability of disease with a given result. It goes on to describe an important drawback of predictive values, namely that they

Predictive value of prostatic adenocarcinoma after a negative prostate biopsy

BJU International, 2006
OBJECTIVE To investigate the predictive value (PV) for all prostate cancers and for clinically significant cancer undiagnosed after a 10‐core biopsy protocol, as the 10‐core transrectal ultrasonography‐guided biopsy is considered the standard technique of prostatic biopsy due to its high rate of detection of ...

Impact of the endoscopist's experience on the negative predictive value of capsule endoscopy

Gastroenterología y Hepatología (English Edition), 2017
The impact of the accumulated experience of the capsule endoscopy (CE) reader on the accuracy of this test is discussed.To determine whether the negative predictive value of CE findings changes along the learning curve.We reviewed the first 900 CE read by 3 gastroenterologists experienced in endoscopy over 8 years.

Effect of verification bias on positive and negative predictive values

Statistics in Medicine, 1994
AbstractThe pairing of sensitivity and specificity expresses the efficacy of a test, and positive and negative predictive values measure the accuracy of a diagnostic test when applied to a particular patient. To calculate these measures, one has to know the true disease status of each patient. In practice, however, some patients may not be selected for

Negative predictive value of d-dimer for diagnosis of venous thromboembolism

International Journal of Hematology, 2008
The D-dimer levels are considered to be useful for the diagnosis of thrombosis, and they can be clinically used as a negative predictive value (NPV). However, evidence for the efficacy of diagnosing thrombosis based on the D-dimer levels is still not well established.

Error in the Calculation of the Correct Use of Positive and Negative Predictive Values

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.
