Association of collateral status and clinical outcomes.
| Clinical outcomes | Poor collaterals (n = 109) | Good collaterals (n = 110) | Adjusted ORs (95%CI) | P value |
|---|---|---|---|---|
| mRS at 90 days, n (%) | ||||
| 0–1 | 28 (25.7) | 38 (34.5) | 4.55 (3.17 to 7.24) | <0.001 |
| 0–2 | 52 (47.7) | 64 (58.1) | 4.28 (3.02 to 6.57) | <0.001 |
| 0–3 | 62 (56.9) | 73 (66.3) | 3.65 (2.15 to 6.03) | <0.001 |
| 0–4 | 72 (66.1) | 81 (73.6) | 2.10 (1.25 to 4.37) | 0.001 |
| Death at 90 days, n (%) | 29 (26.6) | 22 (20.0) | 0.87 (0.72 to 0.96) | 0.012 |
Odds ratios (ORs) were adjusted for age, history of diseases, medication use, SBP at hospital arrival, location of intracranial artery occlusion, and the NIHSS at hospital arrival.
