The Escalating Global Burden of motor neuron disease: spatiotemporal trends among older adults, affected factors, and future projections.
Article in American journal of clinical and experimental immunology, 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
objectiveMotor Neuron Disease (MND) is an increasing social health issue, in the cases of adults above 50 years of age, which requires the examination of its multidimensional burden, the spatiotemporal patterns, and the factors that contribute to it.
methodsWe estimated age-standardized prevalence (ASPR), incidence (ASIR), mortality (ASMR), disability-adjusted life years (ASDR), and years lived with disability (ASYLDs) and years of life lost (ASYLLs) in adults aged 50 and older based on Global Burden of Disease (GBD) data 1990-2021. The correlation between Socio-demographic Index (SDI) and disease burden was sought through the analysis of correlation; the relationship between temporal changes and the gave way to joinpoint regression and the Bayesian age-period-cohort (BAPC) models to determine future disease burden.
resultsThe number of MND cases and age-standardized rates (ASRs) increased substantially over the period 1990-2021 with YLLs making up over 95 percent of DALYs. The highest burden was 75-84 years, with the males having a skewed burden. There were positive relationships between SDI where high-SDI regions (such as Australasia, North America, Western Europe) had the greatest burdens. The burdens were highest in Finland, Ireland and Sweden; the smallest countries recorded steep increases in Lithuania and Costa Rica. The analysis of joinpoint showed that global ASIR on the increase (1995-2005) then decreased (2019-2021), high-SDI areas recorded consistent growth. BAPC forecasted the increase in the number of cases even after minimal decrease in ASRs by 2040.
interpretationThe problem of the increasing burden of MND fueled by the aging population and negative prognosis highlights the inequalities between the strata in terms of SDI. The ability to treat increases the burdens in high-income regions. The focus on surveillance, fair prevention, and resources distribution is important. The paper has emphasized the importance of international cooperation to help reduce disparities associated with SDI and maximize interventions.
