Rate of progression of carotid artery stenosis
| Cilostazol (+) | Cilostazol (−) | P | |
|---|---|---|---|
| Stenosis progression in normal side | 6.9% (2/29) | 28.8% (19/66) | 0.03 |
| Restenosis in CAS side | 0% (0/29) | 15.2% (10/66) | 0.03 |
Note:—We classified the initial grade of stenosis in normal side as follows: A, 0–49% stenosis; B, 50–79% stenosis; C, 80–99% stenosis and occlusion. We determined any progression, if category was advanced to a higher category of stenosis. Restenosis was defined 50% stenosis or greater.
