Decision Curve Analysis

When to Use

Use this skill when you need to:

• evaluate whether a binary prediction model adds clinical net benefit across threshold probabilities;
• visualize decision curves and clinical-impact curves from a clinical cohort;
• export an auditable DCA model object together with summary text and PDFs.

Typical user requests:

• "Run decision-curve analysis on this binary outcome and risk-score dataset."
• "Generate DCA and clinical-impact plots for this prediction model."
• "Compare net benefit across thresholds for this case-control cohort."
