Receiver operating characteristic (ROC) curves for prediction of acute myocardial infarction or death. ROC curves for unadjusted (solid line) and adjusted (dotted line) stress lung-heart-ratios (sLHR) are plotted in relation to adverse outcomes. (A) Combined stress methods (adjusted for sex, age and systolic blood pressure). (B) Subgroup of patients undergoing treadmill exercise only (adjusted for sex, age and peak double product).
