Table 5 One-, three- and five-year survival rates in the two groups

Time	Group	Survival		Survival rate, %	χ2	P value
		Yes	No
1 yr	A	796	141	84.95	0.326	0.568
	B	245	62	79.80
3 yr	A	726	211	77.48	0.364	0.564
	B	219	88	71.33
5 yr	A	632	305	67.44	0.178	0.673
	B	193	114	62.86

The 1-, 3-, and 5-year survival rates did not differ between groups A and B (χ² = 0.326, P = 0.568; χ² = 0.364, P = 0.564 and χ² = 0.178, P = 0.673, respectively).
