Now, let us calculate the false/error rates of the SLR test when compared against the gold standard MRI test results (1). The false positive rate of the SLR test (Type I error) is calculated as the ra...
In this section, the true positive and negatives rates of diagnosing a disease using a clinical test (eg., SLR) compared against a gold standard test (in this instance, MRI) will be calculated. Let us...
The receiver operating characteristic (ROC) curve is a measure of diagnostic efficiency, which is obtained by graphically plotting a series of true positive rates (sensitivity) against false positive ...
Pre-test Probability is the likelihood that a patient has a particular disease before any diagnostic tests are performed. The pre-test probability and disease prevalence are related concepts and it is...
The collection and synthesis of clinically relevant data including signs, symptoms, complaints, psychological status and social circumstances help make a formal diagnosis. The challenge is how to make...
