Clinical significance of expression of tissue factor and tissue factor pathway inhibitor in ulcerative colitis

Table 1 Expression of tissue factor in ulcerative colitis and normal colon tissues

Group	Number of total cases	Number of positive cases	Number of negative cases	Positive rate
Experimental	30	19	11	63%
Control	30	10	20	33%

The data indicated that the positive rate of tissue factor expression in ulcerative colitis was higher than that in normal colon tissues. χ² = 5.41, P < 0.05 vs control.
