Nomogram of factors associated with the final model for diagnosing postoperative HB, including preoperative total bilirubin, aortic clamp time and RBC transfusion. First, a point was found for each variable on the uppermost rule; then, all scores were added together, and the total number of points was collected. Finally, the corresponding predicted probability of HB was found on the lowest rule
