Venous and arterial diameters at baseline and at 30, 60, 90, and 120 minutes after sildenafil administration. Data are presented as mean (SD) (n=10)
| Time after sildenafil administration (minutes) | Venous diameter (arbitrary units) | p Value | Arterial diameter (arbitrary units) | p Value |
|---|---|---|---|---|
| One way ANOVA for repeated measures for venous diameter: F(4.36) = 10.9, p<0.0001; for arterial diameter: F(4.36) = 12.0, p<0.0001. p Values indicate significance of difference between values at baseline and sildenafil administration (*p<0.005). | ||||
