Perioperative Elevation in Cell-Free DNA Levels in Patients Undergoing Cardiac Surgery: Possible Contribution of Neutrophil Extracellular Traps to Perioperative Renal Dysfunction

Figure 5

Relationship between the activity of deoxyribonuclease (DNase) and the neutrophil activation marker S100A12. (a) Baseline (), (b) immediately after surgery (PostOp, ), and (c) the day after surgery (POD-1, ). (d) When the data from all three time points (baseline, PostOp, and POD-1) were combined (merge), a moderate correlation between these two variables was observed (, ). X marks, baseline; open circles, PostOp; open squares, POD-1. : correlation coefficient calculated from Spearman’s tests.
