Trends of hospital-based reporting of intracranial neoplasms in Nigeria from 1960 to 2024: A systematic review and pooled analysis of literatures.
Article in Neuro-oncology advances. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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: Intracranial neoplasms, encompassing benign and malignant tumors, remain a significant health concern worldwide. This review systematically examines hospital-based reports of intracranial neoplasms in Nigeria from 1960 to July 2024, highlighting their distribution, demographics, and temporal trends. Methods: Following PRISMA guidelines, studies published from 1960 onward were identified through PubMed, Google Scholar, and African Journals Online. Eligible studies reported incidence, prevalence, or demographic data of intracranial neoplasms in Nigeria. Extracted data were pooled for meta-analysis to estimate aggregated incidence and prevalence. Results: Forty-five studies comprising 3517 cases were included. Pooled extrapolated prevalence was 3.22 (95% CI: 1.66-5.22), while compounded 10 yearly incidence was 3.66 (95% CI: 1.67-6.32). Reported incidence increased from 2.18% (1960-1969) to 4.08% (2000-2009) and 4.84% (2010-2019). Gliomas, meningiomas, and pituitary adenomas were the most frequent tumors. Among adults, meningioma predominated, followed by glioma and pituitary adenoma, whereas in children, gliomas were most common, followed by medulloblastoma and craniopharyngioma. Male predominance was observed (male-to-female ratio 1.17:1), with peak cases in the fourth to sixth decades. Regionally, southern Nigeria (southeast and southwest) showed higher incidence, reflecting disparities in diagnostic capacity and reporting compared with the north. Conclusion: Reported intracranial neoplasms in Nigeria have increased over the decades, with a prevalence of 3.22 and distinct demographic and geographic patterns. Strengthening diagnostic infrastructure, improving reporting systems, and establishing a national registry are essential for better understanding and management.
