Clinical value of liver and spleen shear wave velocity in predicting the prognosis of patients with portal hypertension

Table 1 Comparison of the liver shear wave velocity values of the two groups at the 1^st week and at the 3^rd and 9^th month after treatment

Group	1st wk after treatment, m/s	3rd mo after treatment, m/s	9th mo after treatment, m/s
Favorable prognosis group	1.88 ± 0.39	1.70 ± 0.41	1.67 ± 0.38
Unfavorable prognosis group	1.84 ± 0.43	1.92 ± 0.43	2.08 ± 0.35
t	0.384	2.068	4.455
P value	0.702	0.043	0.000

Data are presented as mean ± SD. (1) F_{within group} = 2.106, P_{within group} = 0.039; (2) F_{between groups} = 2.193, P_{between groups} = 0.032; (3) F_interaction = 2.457, P_interaction = 0.017.

Favorable prognosis group	3.82 ± 0.44	3.71 ± 0.42	3.55 ± 0.34
Unfavorable prognosis group	3.83 ± 0.46	4.06 ± 0.44	4.29 ± 0.30
t	0.088	3.213	9.178
P value	0.930	0.002	0.000

Data are presented as mean ± SD. (1) F_{within group} = 2.544, P_{within group} = 0.013; (2) F_{between groups} = 8.431, P_{between groups} = 0.000; (3) F_interaction = 3.422, P_interaction = 0.001.
