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

Table 7 Predictive accuracy of the best cutoff value of spleen diameter and Platelet count-spleen diameter ratio in the diagnosis of large esophageal varices

Non-invasive marker	Cut-off value	Sensitivity (%)	Specificity (%)	AUROC (95%CI)	P value	PPV (%)	NPV (%)	Accuracy (%)
Spleen diameter	140.5 mm	78.95	60.76	0.695 (0.595-0.795)	0.001a	49.18	85.71	66.67
PC/SD	696.5	63.16	55.7	0.595 (0.488-0.702)	0.095	40.68	75.86	58.12
