Hepatic venous pressure gradient: Inaccurately estimates portal venous pressure gradient in alcoholic cirrhosis and portal hypertension

Table 3 Relationships between wedged hepatic venous pressure and portal venous pressure and between hepatic venous pressure gradient and portal venous pressure gradient in patients with and without collateral branches

	WHVP and PVP				HVPG and PPG
	r	R2	P value	95% LoA (mmHg)	r	R2	P value	95% LoA (mmHg)
With collateral branches (n = 26)	0.303	0.092	0.133	-3.16-31.31	0.208	0.043	0.309	-2.25-34.40
No collateral branch (n = 108)	0.368	0.135	< 0.001	-13.88-19.07	0.263	0.069	0.006	-13.41-24.95
Total (n = 134)	0.270	0.073	0.002	-23.64-13.99	0.201	0.040	0.020	-28.35-12.80

LoA: Limits of agreement; WHVP: Wedged hepatic venous pressure; PVP: Portal venous pressure; HVPG: Hepatic venous pressure gradient; PPG: Portal venous pressure gradient.
