Figure 1 A, The direct effect of independent variable (X) on dependent variable (Y) denoted as C. B, The effect of X on Y through a mediator (M) where the association between X and M is denoted as “a”, the association between M and Y is denoted as “b”, and the association of X and M to Y is denoted as Ć, such that C = Ć + ab.

Figure 2 Distribution of urinary biomarkers in different groups by blood transfusion is shown in box plot. The bars represent the interquartile range, and the solid lines in the bars represent the median values of first postoperative urinary IL-18 and urinary NGAL. The median values of both urinary IL-18 and urinary NGAL were significantly elevated in those who received more than 2 PRBC units compared with those who received less than 2 PRBC units (P values for Wilcoxon test <.0001 and <.0001, respectively) or no blood (P values for Wilcoxon test <.0001 and <.0001, respectively). *No blood versus more than 2 PRBC, P < ˄Less than 2 PRBC versus more than 2 PRBC, P < IL, Interleukin; NGAL, neutrophil gelatinase-associated lipocalin; PRBC, packed red blood cell.
