Splenic artery internal diameter (mm)	5.35 (4.67-6.18)	4.60 (4.32-5.32)	0.0021
Proper hepatic artery internal diameter (mm)	3.63 (2.97-4.43)	3.72 (3.14-4.19)	0.830

¹Indicates significant difference between patients with cirrhosis and portal hypertension and healthy controls. Data were presented as number (%) for sex, cause of cirrhosis, and level of liver function; mean ± SD for age; and median (interquartile range: Q1-Q3) for the internal diameters of the splenic artery and proper hepatic artery and the splenic artery internal diameter/proper hepatic artery internal diameter (S/P) ratio because data were not normally distributed. Data of patients with cirrhosis and healthy controls were compared using Pearson χ² for sex, two-sample t test for age, and Mann-Whitney U test for S/P ratio, respectively. NA: Not assessed.
