Table 3 ROC curve analysis of diagnostic accuracy of NLR, MPV, and combined NLR + MPV to detect SBP

From: Validation of the diagnostic accuracy of neutrophil to lymphocyte ratio (NLR) and mean platelet volume (MPV) in cirrhotic patients with spontaneous bacterial peritonitis

Variable	NLR	MPV (fL)	NLR + MPV
AUC (95% CI)	0.872 (0.83–0.913)	0.678 (0.616–0.74)	0.892 (0.854–0.931)
Cut-off	> 5.6	> 8.8	> 14.5
Sensitivity	78%	62%	79%
Specificity	81%	63%	81%
PPV	68%	47%	69%
NPV	87%	75%	88%
Accuracy	80%	62%	80%
P value	< 0.001	< 0.001	< 0.001

AUC area under the curve, PPV positive predictive value, NPV negative predictive value, NLR neutrophil to lymphocyte ratio, MPV mean platelet volume
