Accuracy of suPAR and lactic acid in diagnosing sepsis in elderly patients

Biomarker	Cutoff value	AUC (95% CI)	Sensitivity	Specificity	PPV	NPV	p value
suPAR (mg/dl)	≥4.37	0.99 (0.93 to 1.0)	97.5%	90.0%	90.7%	97.3%	0.001*
Lactic acid (mmol/l)	≥1.95	0.84 (0.74 to 0.91)	67.5%	87.5%	84.4%	72.9%	0.001*

Abbreviations: AUC, area under ROC (receiver operating characteristic) curve; CI, confidence interval; NPV, negative predictive value; PPV, positive predictive value
