Surgical outcomes and clinical profile of pediatric brain tumors: A 3-year retrospective analysis.
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: Pediatric brain tumors represent a major challenge in neuro-oncology, with significant morbidity and mortality in resource-limited settings. Data on surgical management and outcomes in Guinea remain extremely limited. This study aims to describe the clinical characteristics, surgical management, and short-term outcomes of pediatric brain tumor patients treated at the University Hospital of Conakry, Guinea. Methods: This retrospective descriptive study included all patients aged 0-18 years who underwent craniotomy for brain tumor resection at the CHU of Conakry from November 2022 to October 2024. Variables analyzed included demographics, clinical presentation, diagnostic and surgical delays, tumor characteristics, extent of resection, perioperative complications, and outcome at 2-month follow-up. Favorable outcome was defined as a modified Rankin Scale score of 3 or less. Results: Thirty-two patients were included (17 males, 15 females; median age 8 years). Headache and vomiting were the most common presenting symptoms (50%). The median diagnostic delay was 7 months, and surgical delay was 3 weeks. Posterior fossa tumors predominated (59%), with medulloblastoma being the most common histology (22%), followed by pilocytic astrocytoma (19%) and ependymoma (16%). Total resection was achieved in only 9 patients (28%). Postoperative complications occurred in 24 patients (75%). At 2-month follow-up, 8 patients (25%) had favorable outcomes, while 24 (75%) had unfavorable outcomes including 15 deaths. The World Health Organization performance score was an independent predictor of mortality ( Conclusion: This study highlights significant challenges in managing pediatric brain tumors in Guinea, characterized by prolonged diagnostic delays, low rates of complete resection, and high morbidity and mortality. These findings underscore the urgent need for improved early detection systems, enhanced neurosurgical infrastructure, and access to adjuvant therapies.
