Platelet counts to spleen diameter ratio: A promising noninvasive tool for predicting esophageal varices in cirrhosis patients

Table 5 Predictive accuracy of the best cutoff value of platelet count, spleen diameter, and platelet count-spleen diameter ratio in the diagnosis of esophageal varices

Non-invasive markers	Cut-off value	Sensitivity (%)	Specificity (%)	AUROC (95%CI)	P value	PPV (%)	NPV (%)	Accuracy (%)
Platelet count	138000/mL	82.05	69.57	0.815 (0.718-0.913)	< 0.001	93.20	43.24	80
Spleen diameter	120.5 mm	83.76	47.83	0.712 (0.605-0.820)	0.001	89.09	36.67	77.86
PC/SD	1118.74	86.32	69.57	0.835 (0.736-0.934)	< 0.001	93.52	50	83.57

AUROC: Area under the receiver operating characteristic curve; PC/SD: Platelet count-spleen diameter ratio; PPV: Positive predictive value; NPV: Negative predictive value.
