WebA discriminant function analysis was performed that generated the equation: D = 2.68 (ratio of portal vein to splenic vein diameters) + 0.187 (gradient of portal vein to splenic vein diameters, in mm) - 4.152. This equation had a very high sensitivity, of 95%, but low specificity, of 26.3%, in predicting the presence of esophageal varices. WebA statistically significant association was declared at P-value < 0.05. Results: Mean portal vein diameter for CLD patients was 17.03± 1.97 mm with a range of 12.8− 20.8mm and 10.79± 1.27mm with a range of 7.70– 13.25mm for the control group.
