Background and Purpose- There is contradictory evidence on the impact of the stroke side (hemisphere) on outcomes. We investigated any effect modification by laterality on stroke patients' outcomes in recent endovascular trials. Methods- Individual patient-level data were combined in this meta-analysis of all patients included in randomized trials comparing endovascular thrombectomy predominantly done with stent retrievers with standard care in anterior circulation ischemic patients with stroke (HERMES [Highly Effective Reperfusion Using Multiple Endovascular Devices] Collaboration). We stratified the 90-day functional outcome assessed by ordinal analysis of the modified Rankin Scale accordi..
