Differences of paxillin staining index in different group of human colorectal cancers

	Group	N	Staining index for paxillin	Value of statistics	P
Well-differentiated CRC	Group I	42	6.295±2.488	χ2 = 41.245	<0.001*
Moderately differentiated CRC	Group II	51	6.708 ± 2.193
Poorly differentiated CRC	Group III	52	9.849 ± 1.932
Lymph node metastatic foci	Group IV	37	10.020 ± 1.450

∗P < 0.05: statistically significant. P: difference among the group; P1: difference between groups I and II =0.395; P2: difference between groups II and III) < 0.001; P3: difference between groups III and IV = 0.653; P4: difference between groups I and IV < 0.001; P5: difference between groups II and IV < 0.001. CRC: colorectal cancer.
