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

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.

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.

Precision and negative predictive value of links between ClinicalTrials.gov and PubMed.

AMIA ... Annual Symposium proceedings. AMIA Symposium, 2013
One of the goals of translational science is to shorten the time from discovery to clinical use. Clinical trial registries were established to increase transparency in completed and ongoing clinical trials, and they support linking trials with resulting publications.

[Sensitivity, specificity, positive and negative predictive value].

Die Rehabilitation, 2005
What does it mean that a screening test has a sensitivity of 80 % and a specificity of 80 %? What conclusion can be drawn as to the probability of a patient tested positive having the target disorder? Is this probability dependent on the prevalence of the target disorder? These are the questions addressed in the present paper. The classical concepts of
