We use the positive predictive value and negative predictive value of a test to summarize that test’s predictive ability.

Results: 6 studies including 708 CD117-positive GIST patients were eligible for analysis of positive predictive value of KIT immunostaining for KIT mutations and 5 studies including 47 CD117-negative ...

However, considerably less attention has been given to the study of the effect of the positivity threshold on the predictive value of a test. In this paper we present methods for the joint study of ...

Positive and negative predictive values of a diagnostic test are key clinically relevant measures of test accuracy. Surprisingly, statistical methods for comparing tests with regard to these ...

The Predictive Value of a CXR in Suspected Pneumonia Clinicians often face uncertainty about whether they can rely on a negative chest x-ray (CXR) to rule out pneumonia in a child, even when other ...

Although the sensitivity and specificity of a test remains static over time, the prevalence of disease in the community will impact the predictive value of a positive or negative result.
