Table 1.

Sections stained positive for the various vascular endothelial growth factor (VEGF) isoforms

Tissue type	N	VEGF-A (95% CI)	VEGF-B (95% CI)	VEGF-C (95% CI)	Overall p value
Uterine arteries	15	40% (15% to 65%)	73% (55% to 91%)	60% (35% to 85%)	0.18
Saphenous veins	15	33% (9% to 57%)	0	40% (15% to 65%)	0.02
Atherosclerotic arteries*	30	60% (43% to 77%)	50% (41% to 59%)	46% (28% to 64%)	0.56
Overall p value		0.18	<0.001	0.53

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