ROC curves for sex-adjusted logistic regression analyses of patient status with respect to suPAR, CRP, and the combination of suPAR and CRP; logistic models stratified by the interval pre-OP and all post-OP intervals combined (overall post-OP); AUC and 95% CI for pre-OP and for overall post-OP are 0.88 (95% CI: 0.76–1.00) and 0.84 (95% CI: 0.71–0.97) for suPAR (a, b), 0.93 (95% CI: 0.85–1.00) and 0.77 (95% CI: 0.62–0.93) for CRP (c, d), and 0.98 (95% CI: 0.96–1.00) and 0.91 (95% CI: 0.82–1.00) for the combination of suPAR and CRP (e, f), respectively
