BACKGROUND AND PURPOSE: The @entity2478 ( @entity2478 ) has been recently introduced as a metric for rating the collateral circulation of @entity385 patients. Multiple studies in the last five years have evaluated the correlation of good @entity2478 with clinical outcomes and suggested the use of @entity2478 in selecting patients for endovascular treatment. We performed a meta-analysis of these studies comparing @entity2478 with clinical outcomes. METHODS: We conducted a computerized search of three databases from January 2011 to November 2015 for studies related to @entity2478 and outcomes. A @entity2478 = 0 or 1 is considered poor (pCIS) and a @entity2478 = 2 or 3 is considered favorable (fCIS). Using random-effect meta-analysis, we evaluated the relationship of @entity2478 to neurological outcome (modified Rankin scale score <=  2), recanalization, and post-treatment @entity548 . Meta-regression analysis of good neurological outcome was performed for adjusting baseline National Institutes of Health @entity64 Scale (NIHSS) between groups. RESULTS: Six studies totaling 338 patients (212 with fCISs and 126 with pCISs) were included in the analysis. Patients with fCIS had higher likelihood of good neurological outcome [relative risk (RR) = 3.03; confidence interval (CI) = 95%, 2.05-4.47; p < 0.001] and lower risk of post-treatment @entity548 (RR = 0.38; CI = 95%, 0.19-0.93; p = 0.04) as compared with patients in the pCIS group. When adjusting for baseline NIHSS, patients with fCIS had higher RR of good neurological outcome when compared with those with pCIS (RR = 2.94; CI = 95%, 1.23-7, p < 0.0001). Favorable @entity2478 was not associated with higher rates of recanalization. CONCLUSIONS: Observational evidence suggests that acute @entity385 patients with fCIS may have higher rates of good neurological outcomes compared with patients with pCIS, independent of baseline NIHSS. @entity2478 may be used as another tool to select patients for endovascular treatment of acute @entity385 .
