Let us continue using the data from the study by Capra et al (1). The likelihood ratio is the percentage of diseased individuals with a given test result divided by the percentage of healthy individua...
Let us continue our Predictive Values analysis using data from Capra et al (1). After a confirmed MRI diagnosis, we may have the following questions: What is the probability that the patient with a po...
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...
Pre-test Probability: It is defined as the probability of a patient having the suspected disease before application of a diagnostic test. Determining the pre-test probability is the first step in maki...
