Segmenting the Global Layers of Malignant Meningioma: A Population-Based Study of Incidence, Risk Factors, and Temporal Trends.
Article in Brain and behavior, 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
backgroundMalignant meningioma is a rare form of primary central nervous system cancer originating from the meninges membrane layers. Current data remain unmapped to cover trends for particular groups globally.
methodsThis study examined the missing gap for its global burden, country-specific incidence, and risk factor trends, stratified by sex and age. Several databases were retrieved for temporal trend analysis and interpretation: Cancer incidence rates from five continents (CI5 Plus), global cancer observatory (GLOBOCAN), global burden of disease (GBD), and the world bank. association between malignant meningioma's and various factors was determined using linear regression. Meningioma incidence trends were estimated using the average annual percentage change (AAPC) with join point regression, including the shift in cancerous meningioma incidence based on corresponding specific variables.
resultNew malignant meningioma cases reported in 2020 were estimated to be 14,832 with aged-standardized rates (ASR) of 1.3 per million population. Considerable variations exist among nations for malignant meningioma's, with the highest ASR found in Latvia (6.9 per million population), compared to a 345-fold difference from the lowest ASR found in Fiji (0.02 per million population). Additionally, chronic disease presence such as smoking and hypertension was associated with higher malignant meningioma incidence. The analysis observed increasing rates of malignant meningioma in younger populations.
conclusionsOverall, this study contributes a global perspective on malignant meningioma incidence and emphasizes further investigation of specific groups that may have been overlooked. The increasing trend of malignant meningioma in younger populations warrants preventive, early diagnosis, and further research initiatives for evidence on risk management.
