Table 4:

Pressure gradients in patient with and without cirrhosis.

Pressure gradient	HVPG, mmHg			PSG, mmHg
	Cirrhosis	None	Total	Cirrhosis	None	Total
0–4 mmHg	8	36	44	5	18	23
5–9 mmHg	22	44	66	16	48	64
10–14 mmHg	32	10	42	29	19	48
15–19 mmHg	13	2	15	13	5	18
20+ mmHg	10	1	11	22	3	25
Total	85	93	178	85	93	178

For HVPG, Chi-square=51.85, df=4, P<0.0001; for PSG, Chi-square=43.15, df=4, P<0.0001. HVPG: Hepatic vein pressure gradient; PSG: Portosystemic gradient.
