Noninvasive Predictors of High-Risk Varices in Patients with Non-Cirrhotic Portal Hypertension

Table 3

Performances of spleen size and PSL in predicting HRV at gastroscopy within 12 months in patients with NCPH. Sensitivity, specificity, PPV, and NPV values are calculated for a threshold of >17.2cm for spleen size and ≤ 5.21 for PSL, with HRV prevalence of 30%. AUROC, area under receiver-operator characteristic curve; PPV, positive predictive value; NPV, negative predictive value; PSL, platelet count-spleen length ratio.

Variable	AUROC (95% CI)	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
Spleen size	0.809 (0.658 – 0.913)	78.57	64.29	48.53	87.50
PSL	0.706 (0.541 – 0.839)	78.57	61.54	46.68	87.01
