Can the use of clean energy improve the cognitive ability of the rural elderly? Evidence from clean heating policy in northern China.
Article in BMC geriatrics, 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
The clean transformation of traditional energy sources is of great significance for the formation and development of human capital in rural areas. We use 5-wave survey from the China Health and Retirement Longitudinal Study (CHARLS) between 2011 and 2020, and based on the quasi-experiment of the "winter clean heating" policy in northern regions implemented by the Chinese government, construct a staggered difference-in-differences (DID) model to estimate the impact of large-scale clean energy use in northern rural China on cognitive impairment among the elderly. We find that the clean heating policy improved the average cognitive ability of the elderly in rural northern China by 3.3%. This policy has a positive impact on the cognitive ability of the elderly by increasing the likelihood of clean energy use in rural households and improving local air quality. Heterogeneity studies find that the "winter clean heating" policy has a more pronounced effect on elderly women with less education levels and those living with their children. Our study provides empirical evidence for the formulation of energy transition and clean heating policies in developing countries.
