Data Leakage in Clinical Prediction Models: When the Model Learns the Future
A practical guide to data leakage in clinical prediction models for clinical researchers. Covers post-outcome features, workflow proxies, validation traps, and what reviewers should demand before trusting a headline AUC.
Net Reclassification Improvement: When a New Biomarker Wins by Moving Patients Between the Wrong Boxes
A practical guide to net reclassification improvement for clinical researchers. Covers event and non-event NRI, arbitrary risk categories, overtreatment traps, and what reviewers should demand before trusting claims that a new model improved classification.
Decision Curve Analysis: When a Better AUC Still Makes Worse Clinical Decisions
A practical guide to decision curve analysis for clinical researchers. Covers net benefit, threshold probability, when prediction models fail to beat treat-all or treat-none strategies, and what reviewers should demand before trusting claims of clinical utility.
