Flow Diversion for Anterior Communicating Artery Aneurysms: Systematic Review and Meta-Analysis.
Article in Stroke (Hoboken, N.J.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAnterior communicating artery (ACoA) aneurysms are associated with a higher risk of rupture. Flow diverters are considered a first-line treatment for intracranial aneurysms. However, the safety and efficacy of ACoA aneurysms are less established. This systematic review and meta-analysis aimed to evaluate the safety and effectiveness of flow diverters for ACoA aneurysms.
methodsWe conducted a systematic search from inception until June 2025. The primary effectiveness outcome was the complete occlusion rate at last follow-up, defined by the Raymond-Roy or O'Kelly-Marotta scales, and the primary safety outcome was mortality. Secondary safety outcomes included good functional outcome and major and minor neurological complications. Pooled estimates were calculated using a random-effects model. Subgroup analysis was performed based on follow-up time.
resultsFifteen studies were included (involving 350 patients with 358 ACoA aneurysms). The complete occlusion rate at last follow-up was 84.29% (95% CI, 79.36-88.22;
conclusionsOur results suggest that flow diverters could represent a potential treatment option for ACoA aneurysms, given the observed complete occlusion rate at last follow-up. However, larger prospective trials are required to further evaluate these findings.
