Figure 3.

Biomarkers are elevated post-cardiopulmonary bypass surgery (CPB) in AKI-positive patients and remain elevated at long-term follow-up (F/U) compared to healthy age-matched patients. Median biomarker concentrations at pre-CPB baseline were compared with those 24 hours after CPB (*P<0.05). Median biomarker concentrations at long-term follow-up were compared with those 24 hours after CPB (#P<0.05). Median biomarker concentrations at long-term follow-up were compared with pre-CPB baseline values ($P<0.05). Finally, median biomarker concentrations at long-term follow-up were compared with those of healthy age-matched controls (+P<0.05). Error bars represent 25th and 75th percentiles. * denotes P value for comparison between baseline pre-CPB and 24-hour post-CPB biomarker concentrations; # denotes P value for comparison between long-term and 24-hour post-CPB biomarker concentrations; $ denotes P value for comparison between long-term and pre-CPB biomarker concentrations; + denotes P value for comparison between long-term and healthy age-matched control biomarker concentrations. Cr, creatinine; KIM-1, kidney injury molecule-1; L-FABP, liver fatty acid–binding protein; NGAL, neutrophil gelatinase-associated lipocalin.
