|---|---|---|---|---|
| Arterial Regions of Endothelial Cell Isolation | Normal | Hypercholesterolemic | Fisher's exact P value | |
| Atherosusceptible regions | ||||
| AA | 1-cm2 susceptible region located at the inner-curve and lateral walls of the aortic arch | 1/6 | 5/5 | 0.013 |
| RB | 0.5 cm of proximal susceptible region of the renal artery | |||
| AbA | 1-cm2 susceptible region 2 cm distal to the branching of the renal artery | 1/4 | 5/5 | 0.048 |
| Atheroprotected regions | ||||
| C | 1-cm2 protected region in the straight section of the artery | 0/5 | 1/5 | 0.500 |
