Table 2.

The portosystemic pressure gradient before and after transjugular intrahepatic portosystemic shunt was significantly different in the two groups

	PPG before TIPS (mmHg)	PPG after TIPS (mmHg)	Number	t	df	P-value	SD of difference	SEM of difference	R squared
TIPS-¹²⁵I group	26.96 ± 5.73	13.1 ± 5.9	40	20.88	39	< 0.0001	4.367	0.6905	0.9179
TIPS only group	26.12 ± 5	12.6 ± 5.4	45	22.94	44	0.0002	4.089	0.6096	0.9228

TIPS: Transjugular intrahepatic portosystemic shunt; PPG: Portosystemic pressure gradient.
