Relation between portosystemic pressure gradient (PPG) and portal vein diameter 17 PV diameter PPG < 14 mm (n = 19) ≥ 14 mm (n = 29) p Average PPG (mmHg) 23.0 ± 5.9 26.2 ± 6.3 > 0.05 Comment: The mean PPG of the group with PV diameter ≥ 14 mm was higher than the group with PV diameter <14 mm, but the difference was not statistically significant with p> 0.05.
