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
Objective: Exposure to household air pollution from solid fuels (HAP) increases stroke risk, affecting approximately 3 billion people worldwide and posing a significant challenge to public health. This study assessed trends in the HAP-related global stroke burden from 1990 to 2021 and quantified associated health inequalities. Methods: Data on HAP-attributable stroke disability-adjusted life years (DALYs) and deaths from 1990 to 2021 at global, regional, and national levels were derived from the Global Burden of Disease (GBD) 2021. The estimated annual percentage change (EAPC) was employed to evaluate temporal trends. Decomposition analysis elucidated the primary drivers of burden changes. Cross-country inequality was examined by incorporating the Sociodemographic Index (SDI), and future disease burden was projected. Results: From 1990 to 2021, the age-standardized rates (ASR) of DALYs and deaths from HAP-related stroke declined globally, although significant geographic heterogeneity persisted. Compared with high SDI regions, lower SDI areas bore a heavier burden, with countries such as Zimbabwe and Lesotho experiencing the most notable increases. Furthermore, the share of global ischemic stroke burden increased, whereas intracerebral hemorrhage remained the dominant contributor. Decomposition analysis revealed that population growth consistently served as the main driver of burden increases in low-middle and low SDI areas. Notably, stroke burden was disproportionately concentrated in lower SDI nations, especially for the subarachnoid hemorrhage subtype. Projections suggested that by 2035, the global HAP-related stroke burden would increase, with the ischemic stroke subtype exhibiting the greatest growth. Conclusion: Although the global HAP-related stroke burden has reduced, significant regional and population disparities persist, along with severe health inequities. Therefore, emphasis should be placed on improving household energy supply and healthcare resource allocation in low-development regions to reduce preventable health inequities.
