Optimal timing of oral anticoagulation initiation in patients with acute ischaemic stroke and atrial fibrillation: a comprehensive meta-analysis and systematic review.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The optimal timing for initiating direct oral anticoagulants (DOACs) for secondary stroke prevention in patients with atrial fibrillation and acute ischaemic stroke remains controversial due to concerns about haemorrhagic transformation. This study aimed to analyse the efficacy and safety of early versus late DOAC initiation. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review was conducted, searching major databases (PubMed, Embase, Cochrane Library and ClinicalTrials.gov) up to May 2024. A total of 11 studies were identified, comprising nine cohort studies (75.5% weight) and two randomised controlled trials (RCTs) (24.5% weight), involving 13 020 participants. The early DOAC group (mean initiation 3.5±1.29 days) included 6250 participants, while the late group (5.7±1.25 days) had 6770 participants. Outcome measures included recurrent ischaemic stroke (RIS), intracranial haemorrhage (ICH), systemic embolism, major haemorrhage (MH), non-major haemorrhage (NMH) and all-cause mortality. Statistical analysis using the Cochrane Review Manager calculated ORs and 95% CIs via the Mantel-Haenszel random effects model. This pooled meta-analysis revealed that the early DOAC group had lower rates of RIS (2.2% vs 2.9%, OR 0.72, 95% CI 0.52 to 0.98, p=0.04, I
