Nomogram for the prediction of AKI based on a multivariable model. The nomogram allows users to obtain the risk of AKI corresponding to a patient's combination of variables. Points are assigned for each predictor by drawing a straight line upward from the corresponding value to the “points” line. Then, the points for each of the predictors are added, and the number is located on the “total points” axis. A line drawn straight down leads to the patient's probability of AKI. Normal representations of UA or sCr levels were within the thresholds of the laboratory. Elevated representations of UA or sCr levels were within the upper limits of the normal range.
