Figure 2. Adjusted Odds Ratios for Moderate to Severe Acute Kidney Injury (AKI) and AKI Requiring Dialysis Within 72 Hours of Surgery in the Derivation Cohort (n = 58 526) .

Figure 2.

The shaded area represents the 95% CI from the restricted cubic spline models. All plots were centered at median values for the respective variables. The odds ratio for each variable was adjusted for the median values of other variables in the model: preoperative serum creatinine at 1 mg/dL, serum albumin at 2.9 mg/dL, serum bicarbonate at 23 mmol/L, blood urea nitrogen at 15 mg/dL, change in serum creatinine at −0.06 mg/dL, serum potassium at 4.4 mmol/L, serum sodium at 138 mmol/L, and time from end of the operation to metabolic panel blood draw at 10 hours. Boxplots display the laboratory parameter distribution with or without AKI along the shared x-axis of each plot; boxes show the IQR, with the line representing the median point, box edges representing first and third quartiles, and whiskers extending to the value closest to 1.5 times the IQR (more extreme values not plotted).
