Slopes of a receiver operating characteristic curve and likelihood ratios for a diagnostic test.
This paper clarifies two important concepts in clinical epidemiology: the slope of a receiver operating characteristic (ROC) curve and the likelihood ratio. It points out that there are three types of slopes in an ROC curve--the tangent at a point on the curve, the slope between the origin and a point on the curve, and the slope between two points on the curve. It also points out that there are...
متن کاملReceiver Operating Characteristic (ROC) Curve Analysis for Medical Diagnostic Test Evaluation
This review provides the basic principle and rational for ROC analysis of rating and continuous diagnostic test results versus a gold standard. Derived indexes of accuracy, in particular area under the curve (AUC) has a meaningful interpretation for disease classification from healthy subjects. The methods of estimate of AUC and its testing in single diagnostic test and also comparative studies...
متن کاملStatistical Evaluation of Diagnostic Tests - Part 2 [Pre-test and post-test probability and odds, Likelihood ratios, Receiver Operating Characteristic Curve, Youden's Index and Diagnostic test biases].
I t h e p r e v i o u s a r t i c l e o n t h e s t a t i s t i c a l e v a l u a t i o n of diagnostic tests –Part 1, we u n d e r s t o o d t h e m e a s u r e s o f sensitivity, specificity, positive and negative predictive values. The use of these metrices stems from the fact that no diagnostic test is ever perfect and every time we carry out a test, it will yield one of four possible outco...

متن کاملProperties of the summary receiver operating characteristic (SROC) curve for diagnostic test data.
The summary receiver operating characteristic (SROC) curve has been recommended to represent the performance of a diagnostic test, based on data from a meta-analysis. However, little is known about the basic properties of the SROC curve or its estimate. In this paper, the position of the SROC curve is characterized in terms of the overall diagnostic odds ratio and the magnitude of inter-study h...
