The expression levels of VEGF within osteosarcoma tissues after Wistar rats infected with adenovirus (positive area × OD) (x̅±s)

Groups	Number of slices	VEGF	p1	p2
Ad-VEGF-siRNA-3 group	8	341646.16±131753.84		> 0.05
Ad-Control-siRNA group	9	1325485.62±452693.48	< 0.05
PBS group	7	1452542.18±624145.49	< 0.05

Note: The differences between Ad-VEGF-siRNA group and Ad-Control-siRNA group, Ad-Control-siRNA group were analyzed and shown in p1. The difference between Ad-Control-siRNA group and PBS group was analyzed and shown in p2.
