Treatment-related complications of intracranial aneurysms smaller than 5 mm: A multicenter analysis of 1,519 cases in Latin America.
Article in Surgical neurology international, 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
Background: Small (<5 mm) intracranial aneurysms present a therapeutic challenge due to their low annual rupture risk and uncertainties regarding procedure-related morbidity. Evidence from Latin America remains limited. Methods: We conducted a retrospective multicenter observational study including 1,519 patients treated between 2017 and 2023 in eight referral centers across five Latin American countries. Demographic, clinical, morphological, and treatment-related variables were analyzed. Logistic regression was used to identify independent predictors of treatment-related complications. Results: The overall complication rate was 6%. Surgical treatment showed higher crude complication rates (11%) compared with endovascular therapy (6%), largely reflecting a greater proportion of ruptured aneurysms. Independent predictors of treatment-related complications were a history of aneurysmal subarachnoid hemorrhage (odds ratio [OR] = 5.03), intraparenchymal hematoma before treatment (OR = 3.56), and ruptured aneurysm status (OR = 2.13). Complications were associated with higher mortality (31% vs. 7%; Conclusion: In this first regional multicenter series, treatment of small intracranial aneurysms in Latin America demonstrated low complication rates and favorable safety profiles for both surgical and endovascular techniques. The predictors identified may support clinical decision-making and improve prognostic assessment.
