2 Fig 1 Biomarker levels by AKI status at both preoperative and postoperative timepoints by patient age group (<2 years [A, C] and ≥2 years [B, D]). Blue bars indicate no AKI, red bars indicate stage 1 AKI, and green bars indicate stage 2/3 AKI. “Early post-op time” means 0 to 6 hours postoperative, and “Late post-op” means first non-missing measurement from days 2 to 5 postoperative. Each bar encompasses interquartile range of values; lines are medians. Circles, plus-signs, and crosses are means. (AKI = acute kidney injury; IL-8 = interleukin-8; TNFα = tumor necrosis factor alpha.)

3 Fig 2 Hospital stay, ICU stay, and ventilation lengths in days by biomarker tertiles. The bars indicate median number of days per biomarker tertile. (ICU = intensive care unity; IL-8 = interleukin-8; TNFα = tumor necrosis factor alpha; T = tertile.)

4 Fig 3 Path analysis including the 175 children aged 2 years and older with nonmissing variable values. Arrows denote the effect of the term at the base on the term at the head. Indirect effects are blue, direct effects are orange. Estimated correlation coefficients are listed. “Standardized” means variables were standardized to have a mean of zero and SD of 1 before computing estimates. (CI = confidence interval; CPB = cardiopulmonary bypass; ΔCr = change in creatinine level; IL-8 = interleukin-8; LOV = length of ventilation.; TNFα = tumor necrosis factor alpha.)
