Fig 1 Total costs and length of stay after isolated CABG according to STS score. The lines represent polynomial trend lines. (CABG = coronary artery bypass grafting; STS = Society of Thoracic Surgeons.)

Fig 2 Regression covariates for isolated CABG. Multivariable regression results for (A) total costs and (B) length of stay after the procedure. Reference categories are as follows: white race, no lung disease, elective operation, one vessel disease, no IABP. (BMI = body mass index; CABG = coronary artery bypass grafting; DM = diabetes mellitus; DSWI = deep sternal wound infection; fib = fibrillation; IABP = intraaortic balloon pump; LVEF = left ventricular ejection fraction; MI = myocardial infarction; PAD = peripheral artery disease; PCI = percutaneous coronary intervention; postop = postoperative; reop = repeated operation.)

Fig 3 Calibration plot for (A) preoperative and postoperative cost and (B) length of stay prediction models. The green and dashed orange lines represent polynomial trend curves. Error bars represent the standard error of the mean costs of the (A) observed costs or (B) length of stay.
