The concepts of study population homogeneity, reference and criterion
standards, and study completeness are discussed to help physicians determine
an article's validity. Instruction on calculating prevalence, sensitivity,
specificity, positive and negative predictive values, and likelihood ratios is
provided and applied to a clinical scenario. Study generalizability and the
role of patient values, expectations, and concerns are also addressed.
