Evaluating the Incremental Value of New Biomarkers With Integrated Discrimination Improvement

Practice of Epidemiology Evaluating the Incremental Value of New Biomarkers With Integrated Discrimination Improvement

The integrated discrimination improvement (IDI) index is a popular tool for evaluating the capacity of a marker to predict a binary outcome of interest. Recent reports have proposed that the IDI is more sensitive than other metrics for identifying useful predictive markers. In this article, the authors use simulated data sets and theoretical analysis to investigate the statistical properties of...

Evaluating the Prognostic Value of New Cardiovascular Biomarkers

New predictors of cardiovascular outcomes are widely sought in research settings, and predictive tests are commonly recommended for routine use in cardiovascular clinical care. A number of multivariable scoring systems are in use around the world for assessment of a patient's risk. While such scoring systems are often recommended for clinical use in medical practice guidelines, their actual use...
