Nomograms for predicting the probability of acute kidney injury (AKI) development based on the fitted multiple logistic regression models in patients with urine output during cardiopulmonary bypass (CPB) <4 mL/kg/h (A) and ≥4 mL/kg/h (B). Directions for using the nomogram: The first row is the point assignment for each variable. For an individual patient, each variable is assigned a point value by drawing a vertical line between the exact variable value and the points line. Subsequently, a total point can be obtained by summing all of the assigned points for the variables. Finally, the predictive probability of AKI can be obtained by drawing a vertical line between “total points” and “probability” (the final row). CPB.UO = amount of urine output during CPB (mL/kg//h), intraop.pRBC = number of transfused packed red blood cells during operation, multi.valve surgery = double or triple valve surgery, postop.pRBC = number of transfused packed red blood cells during postoperative 48 hours.
