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

Table 6 Predictive accuracy of the cutoff value of platelet count, spleen diameter, and platelet count-spleen diameter ratio in the diagnosis of compensated cirrhosis

Non-invasive marker	Cut-off value	Sensitivity (%)	Specificity (%)	AUROC (95%CI)	P value	PPV (%)	NPV (%)	Accuracy (%)
Platelet count	119500/mL	73.47	90.48	0.872 (0.785-0.959)	0.001a	94.74	59.38	78.57
Spleen diameter	133.5 mm	59.18	76.19	0.713 (0.591-0.836)	0.005	85.29	44.44	64.29
PC/SD	830.3	69.39	95.24	0.889 (0.805-0.973)	0.001a	97.14	57.14	77.14
