Clinical Research: Usefulness of Diagnostic Tests-Methods, Statistics, Results & Interpretation provides an introductory overview of the research and data analysis methods used to assess the utility of diagnostic tests. After exploring the role of clinical research in informing decisions about patient care, the DVD looks at the tools that can assist investigators in this regard. The DVD also reviews several studies of diagnostic tests that have been conducted that have produced dichotomous outcomes. In that regard, the concepts of sensitivity, specificity, positive/negative prediction values, and likelihood ratios are examined. In addition, the DVD discusses the application of likelihood ratios in clinical practice, as well as explains the underlying factors involved in receiver-operator characteristic curves.
