From: Reduced post-operative DPP4 activity associated with worse patient outcome after cardiac surgery

DPP4 activity levels negatively correlate with post-operative morbidity scores. Correlations between relative serum DPP4 activity levels 12 h post-OP and SAPS II score (a) or SOFA score (b) on the first post-operative day. Data are depicted as linear regression (black line) with 95% confidence intervals (dashed lines). r = Spearman correlation coefficient; two-tailed P-value; *P < 0.05.
