Association between PAD and history of cardiac event using odds ratios (OR). PAD was defined by an ABI value < 0.9 or clinical evidence of PAD, while history of cardiac event was evident after myocardial infarction or coronary revascularisation. OR, sensitivity and specificity are shown for the different modes of ABI calculation. Sensitivity and specificity are given for the 'detection' or 'exclusion', resp., of a history of cardiac events.
