Table 2.

Sections stained positive for the various vascular endothelial growth factor receptors (VEGFRs)

Tissue type	N	VEGFR-1 (95% CI)	VEGFR-2 (95% CI)	VEGFR-3 (95% CI)	Overall p value
Uterine arteries	15	27% (5% to 49%)	53% (28% to 78%)	80% (60% to 100%)	0.02
Saphenous veins	15	93% (80% to 100%)	0	80% (60% to 100%)	<0.001
Atherosclerotic arteries*	30	20% (7% to 34%)	20% (7% to 34%)	83% (70% to 96%)	<0.001
Overall p value		<0.001	0.02	0.95

Percentages and 95% confidence intervals shown in the table correspond to the proportion of sections where positive staining for the various VEGF receptors was detected. The χ² test was used to calculate the p value.
