Sample size for diagnostic accuracy and disease frequency

Sample size for diagnostic accuracy and disease frequency

In considering the sample size of studies with test-based enrollment instead of case-referent sampling, to compare observed post-test probabilities in relation to preselected test outcomes, analogous considerations will apply. [...]for both these situations, the required total sample size will gener...
