Epidemiological trends of burden of brain and CNS cancer at global, regional, and national level: a trend analysis study from 1990 to 2021.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundBrain and central nervous system (CNS) cancers, though relatively rare, contribute substantially to neurological disability and cancer-related mortality worldwide. This study systematically assessed their global, regional, and national trends from 1990 to 2021 and projected burden through 2035 using Global Burden of Disease Study (GBD) 2021 data.
methodsUsing data from the Global Burden of Disease (GBD) 2021 study, we estimated age-standardised incidence rate (ASIR), prevalence rate (ASPR), death rate (ASDR), and DALY rate across 204 countries, 21 regions, and five socio-demographic index (SDI) groups. Trends were analyzed using estimated annual percentage change (EAPC), and future projections were generated using a Bayesian age-period-cohort (BAPC) model.
resultsFrom 1990 to 2021, the global ASIR of brain and CNS cancers increased from 3.75 (95% UI 3.21-4.21) to 4.28 (95% UI 3.71-4.88) per 100,000, with an EAPC of 0.45 (95% CI 0.40-0.49). ASPR rose from 8.66 (95% UI 7.55-9.53) to 12.01 (95% UI 10.54-13.52), while ASDR remained stable, and DALY rates declined from 119.88 (95% UI 99.23-137.57) to 107.91 (95% UI 91.74-125.59). High-income Asia Pacific showed the largest ASIR increase (EAPC 2.02), while Central Asia experienced the highest rise in DALYs (EAPC 1.20). Age and sex disparities were notable, with older adults (≥ 70 years) and males exhibiting higher rates. Projections indicate continued ASIR and ASPR growth, while ASDR and DALY rates decline, and-critically-an increase in the absolute numbers of cases, deaths, and DALYs through 2035 driven by population growth and ageing.
interpretationBrain and CNS cancers show increasing incidence and prevalence globally, with stable mortality and declining DALYs. These trends highlight the need for enhanced early detection, equitable access to care, and targeted interventions across regions. Notwithstanding broadly stable or declining age-standardised rates, absolute counts of cases and deaths are projected to rise to 2035, underscoring the urgency of scaling diagnostic and treatment capacity-particularly in lower-SDI settings.
