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.
