Questionnaire-based high-risk status

1. Questionnaire-based high-risk status decreases discrimination of coronary artery calcium in humans (AUC 0.647 vs. 0.779).

   “dichotomized risk classification showed reduced discrimination for CAC versus a continuous age-smoking model (AUC 0.647 vs. 0.779).”
