Temporal and Geographic Variation in Outcomes After Poor-Grade Aneurysmal Subarachnoid Hemorrhage: A Systematic Review and Meta-analysis

2026-07-02

Abstract excerpt

<h4>Background</h4> Poor-grade aneurysmal subarachnoid hemorrhage (aSAH) remains associated with high mortality and severe disability, yet contemporary outcomes may differ substantially from historical estimates. We performed a systematic review and meta-analysis to evaluate long-term outcomes after poor-grade aSAH and assess temporal, geographic, and treatment-related factors associated with prognosis. <h4>Metho...
