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

Figure 3

Relationship between serum double-strand DNA (dsDNA) concentration and the activity of deoxyribonuclease (DNase). Spearman’s tests were performed at (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.
