Cross-country health inequality in the asthma burden: findings from the global burden of disease study 2021.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundChanges in inequality in the total and risk factor-specific incidence, prevalence, deaths, and disability-adjusted life years (DALYs) of asthma have not been evaluated.
methodsAsthma incidence, prevalence, deaths, and DALYs, and risk factors-related deaths and DALYs rates were extracted from the Global Burden of Disease study 2021. We employed decomposition analysis, encompassing aging, population growth, and epidemiologic changes, to investigate factors influencing incidence, prevalence, deaths, and DALYs of asthma. Besides, the slope inequality index (SII) and relative concentration index (RCI) were used to assess the inequality in the total and risk factor-specific incidence, prevalence, deaths, and DALYs of asthma.
resultsGlobal rates of asthma incidence, prevalence, deaths, and DALYs declined from 1990 to 2021. People aged < 5 years exhibited the highest asthma incidence, and those aged ≥ 70 years old had the highest prevalence, death, and DALYs rates of asthma. Leading drivers of increased number of asthma deaths were aging (127.48%) and population growth (138.99%), but epidemiological change contributed mostly to decreased numbers of asthma incidence, prevalence, and DALYs. Asthma incidence decreased with raising socio-demographic index (SDI), but asthma prevalence increased with increasing SDI. Inequality in asthma incidence and prevalence decreased as indicated by SII and RCI. Besides, asthma deaths and DALYs rates were concentrated in lower SDI regions. Inequality in high body mass index-related asthma death increased and concentrated in lower SDI regions, but inequality in risk factor-specific asthma DALYs all decreased.
conclusionOur findings imply that rates of asthma incidence, prevalence, deaths, and DALYs decreased, but age-specific distribution was not essentially changed. Inequality in asthma incidence and prevalence narrowed, but high body mass index-related asthma death concentrated in lower SDI regions and inequality widened. Healthcare system reforms should focus on primary risk factor and lower SDI regions.
