Collateral Status and Clinical Outcomes after Mechanical Thrombectomy in Patients with Anterior Circulation Occlusion

Table 2

Association of collateral status and clinical outcomes.

Clinical outcomes	Poor collaterals (n = 109)	Good collaterals (n = 110)	Adjusted ORs (95%CI)	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.
