Reduction of portosystemic gradient during transjugular intrahepatic portosystemic shunt achieves good outcome and reduces complications

Table 2 Portosystemic gradient changes in the two groups

Groups	PSG (mmHg)		tvalue	Pvalue
	Before	After
Group A	24.58 ± 2.41	15.72 ± 1.04	11.48	0.012
Group B	25.37 ± 2.54	11.27 ± 2.04	14.25	0.004
	(t value) 0.649	6.382
	(P value) 0.483	0.026
Group C	25.12 ± 3.16	16.15 ± 1.37	12.43	0.016
Group D	24.48 ± 3.24	10.28 ± 1.18	15.47	0.003
	(t value) 0.367	5.734
	(P value) 0.534	0.017

There are differences before and after transjugular intrahepatic portosystemic shunt in the four groups: group A compared with B, and group C compared with D. PSG: Portosystemic gradient.
