Simple Statistical Measures for Diagnostic Accuracy Assessment
Journal of Thoracic OncologyVol. 5Issue 6p763–764Published in issue: June, 2010- Jayawant N. Mandrekar
Cited in Scopus: 35The aim of diagnostic medicine research is to estimate and compare the accuracy of diagnostic tests to provide reliable information about a patient's disease status and thereby influencing patient care.

In this brief report, we discuss these simple statistical measures that are used to quantify the diagnostic ability of a test.
