2. Fig 1
(A) Absolute standardized differences of variables between patients who received statins before the cardiac operation and those who did not. The black open diamonds represent differences before propensity score matching; the blue diamonds represent differences after propensity matching. (B) Mirror histogram of propensity scores for patients who received statins before the cardiac operation (below the horizontal line at 0) and those who did not (above the horizontal line at 0). Matched patients who did and did not receive preoperative statin therapy are subsets of the original patient population and their volumes are shown in grey or blue, respectively. Matched groups have a similar propensity score distribution. (ACC = aortic cross-clamp; ACE = angiotensin-converting enzyme; AMI = acute myocardial infarction; BSA = body surface area; Ca-antagonist = calcium antagonists; COPD = chronic obstructive pulmonary disease; CPB = cardiopulmonary bypass; CVA = cerebrovascular accident; eGFR = estimated glomerular filtration rate; EuroSCORE = European System for Cardiac Operative Risk Evaluation; LMS = left main stem; LVEF = left ventricular ejection fraction; PVD = peripheral vascular disease.)
