====== Decision curve analysis ======


[[Decision]] curve analysis is a method to evaluate [[prediction model]]s and diagnostic tests that was introduced by Vickers and Elkin in a 2006 publication in Medical [[Decision]] Making.

The method sought to overcome the [[limitation]]s of both traditional statistical metrics, such as [[discrimination]] and [[calibration]], which are not directly informative as to clinical value, and full decision analytic approaches, which are too unwieldy to be used in regular biostatistical practice.

[[Decision curve analysis]] showed that the prediction [[nomogram]] of Han et al. for [[spontaneous intracerebral hemorrhage]] was clinically useful. The study delineates a predictive [[nomogram]] combining clinical and imaging features, which can help identify patients who may die
