Global, regional, and national burden of motor neuron disease in adults aged 65 years and older from 1990 to 2021 and forecast to 2040.

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
Aim: Given the significant social burden of motor neuron disease (MND) among elderly patients (aged ≥ 65 years) and the lack of detailed research on its epidemiological characteristics, this study aims to elucidate the temporal trends and distributional characteristics of MND in the elderly from 1990 to 2021, as well as to forecast its future burden. Methods: The age-standardized rates (ASR) and absolute numbers of MND-related incident, prevalent, death, and disability-adjusted life years (DALYs) among older patients (aged ≥ 65 years) globally were derived from the Global Burden of Disease (GBD) study from 1990 to 2021. The data were derived by gender, age group and geographic region. An estimated annual percentage change (EAPC) was estimated to represent temporal trends, and a Bayesian Age-Period-Cohort model was used to forecast the future burden of elderly MND. Results: In 2021, the global ASRs of incidence, prevalence, mortality, and DALYs for elderly MND were 3.63 (95% uncertainty intervals [UI], 2.95-4.36), 11.45 (95% UI, 8.69-14.88), 3.28(95% UI, 2.90-3.61), and 59.92 (95% UI, 53.94-65.53), respectively. Elderly patients those were from high socio-demographic index (SDI) region, as well as males, exhibited the highest burden. From 1990 to 2021, the global ASRs of elderly MND increased, with EAPCs of 0.43 (95% confidence interval [CI], 0.38-0.49), 0.58 (95% CI, 0.48-0.68), 0.90 (95%CI, 0.75-1.06), and 0.84 (95% CI, 0.71-0.96), respectively. Positive correlations were found between sociodemographic index and the burden of elderly MND. Health inequalities were evident across 204 countries and regions, with the inequality slope index raised from 23.46 (95% CI: 18.52-28.40) in 1990 to 80.70 (95% CI: 65.07-96.32) in 2021. Compared to the figures observed in 2021, our forecasts indicate a continued rise in the burden of elderly MND up to 2040, with the projected ASIR expected to reach 3.15 (95% UI, 2.28-4.01) and the ASMR anticipated to be 3.32 (95% UI, 2.11-4.55). Conclusion: The burden of MND among elderly patients is substantial, particularly in high SDI region and among males. From 1990 to 2021, the global burden of elderly MND has exhibited an increasing trend. The burden of elderly MND varies significantly across the world, necessitating more targeted screening strategies and preventive measures to address the issue of elderly MND.
