Objectives

Narrative objectives1

Factor XIa inhibition is an emerging antithrombotic strategy intended to reduce recurrent thrombotic events while preserving physiological hemostasis. Its role in secondary prevention after non-cardioembolic ischemic stroke or high-risk transient ischemic attack (TIA) remains uncertain.

Key inclusion criteria

Studies were deemed eligible for inclusion if they satisfied all of the following criteria: (1) they were double-blind, placebo-controlled randomized clinical trials; (2) they enrolled adults aged 18 years or older with recent non-cardioembolic ischemic stroke or high-risk TIA; and (3) they evaluated an oral or injectable FXIa inhibitor administered alongside background antiplatelet therapy.

Key exclusion criteria

. Studies were excluded if they enrolled patients exclusively for primary prevention, were limited to cardioembolic stroke or atrial fibrillation populations, or employed a nonrandomized design. Additionally, observational studies, case reports, case series, editorials, reviews, and conference abstracts without sufficient outcome data were excluded.
