Admission systemic inflammatory indices and 6-month functional outcome after endovascular thrombectomy for acute ischemic stroke: an exploratory single-center cohort study.

Admission neutrophil-to-lymphocyte ratio, SII, and systemic inflammation response index are associated with 6-month poor outcome after endovascular thrombectomy, but this association is largely explained by stroke severity, with no detectable incremental value beyond National Institutes of Health Stroke Scale.

These exploratory findings are hypothesis-generating and require prospective multicenter validation before clinical use.
