Table 4 Performance of the portal vein diameter, spleen width and the platelet count/spleen width ratio for predicting the presence of EV.

From: Predictors of esophageal varices in patients with HBV-related cirrhosis: a retrospective study

Variable Best Cut-off Se (%) Sp (%) +LR -LR PPV (%) NPV (%) DA (%)
Portal vein diameter (mm) 12 83.5 56.8 1.93 0.29 85.1 53.8 76.7
Spleen width (mm) 46 71.6 75.7 2.94 0.38 89.7 47.5 72.6
Platelet count/Spleen width 1.0513 57.8 67.6 1.78 0.62 84.0 35.2 60.3
  1. Se, sensitivity; Sp, specificity; +LR, positive likelihood ratio; -LR, negative likelihood ratio; PPV, positive predictive value; NPV, negative predictive value; DA, diagnostic accuracy; Prevalence of esophageal varices, 74.7% (109/146)
