Studies evaluating the effect of reperfusion on outcomes

Author (published year)	Study design	No. of patient	Artery	Clinical outcomes	Significance of reperfusion
Mokin et al. (2016) [2] (2011–2015)	Multicenter retrospective	100	VBAO	3-mo mRS 0–2	Successful recanalization is a predictor of good outcome.
Bouslama et al. (2017) [3] (2005–2015)	Two center retrospective	214	VBAO	3-mo mRS 0–2	Reperfusion predicts good outcomes (aOR, 10.80; 95% CI, 1.36–85.96).
Gory et al. (2018) [4] (2010–2016)	Multicenter ETIS registry	100	BAO	3-mo mRS 0–2	Reperfusion predicts good outcome (aOR, 5.64; 95% CI, 1.32–24.06).
