Descriptive epidemiology and surgical outcomes of intracranial tumors in southwestern uganda: a cross-sectional study.
Article in Journal of neuro-oncology, 2025. 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
backgroundThere is a paucity of published data on intracranial tumors in Sub-Saharan Africa (SSA), leaving the true epidemiology of these lesions unclear. To address this gap, we conducted a descriptive epidemiological analysis at Mbarara Regional Referral Hospital (MRRH) in Southwestern Uganda to characterize histological patterns, patient demographics, surgical management, and discharge outcomes.
methodsThis cross-sectional study contains retrospective (2016 – 2020) and prospective (2021 – 2024) descriptive components from clinical records of patients with intracranial tumors. Histology reports were sourced from the Histopathology Unit at MRRH and a private facility, Surgpath Medical Consultants.
resultsWe included data from 364 patients with radiologically confirmed intracranial tumours between 2016 and 2024. The median age was 40 years (Interquartile range IQR: 24–54), and females were 51%. Overall, 92% of patients received Computed Tomography (CT) scans, and tumors were predominantly supratentorial (87% in adults; 61% in pediatrics). The majority (69%) underwent surgical intervention, with meningiomas as the most common histological subtype (33%), followed by adult-type diffuse gliomas (24%) and sellar region tumors (15%). Female preponderance correlated with the high proportion of meningiomas. No regional variation in histology was noted. Survival at discharge was higher among meningioma and benign tumors, with no significant variation by histology.
conclusionsThis study demonstrates a high increasing number of intracranial operated tumors over the years in patients managed at a tertiary hospital in Southwestern Uganda, with demographic and histological patterns broadly comparable to global literature. The findings highlight the need for enhanced neuro-oncology capacity in SSA and serve as a baseline for future studies to improve patient outcomes.
