Short-term exposure to ambient air pollutants increases the mortality risk of chronic kidney disease: a time-stratified case-crossover study in Zhejiang Province.
Article in BMC nephrology, 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
backgroundThe association between air pollutants and mortality from chronic kidney disease (CKD) remains to be further investigated. This study aims to examine the impact of air pollutant exposure on CKD mortality in individuals.
methodsThis study utilized an individual-level, time-stratified case-crossover design to evaluate the association between short-term exposure to air pollutants (PM
resultsThe study found that short-term exposure to all four air pollutants was associated with an increased risk of CKD mortality. The excess risk (ER) per interquartile range (IQR) increase in pollutant concentrations was evaluated across different lag periods. Using multi-day moving average lags (calculated as the mean exposure from the current day up to the specified preceding day), the most prominent ERs were observed for PM2.5 at lag02 (ER: 15.16%, 95% CI: 12.69-17.68), SO
conclusionsThis study revealed a significant association between short-term exposure to air pollutants and CKD mortality in the population of Zhejiang Province. These findings provide novel evidence for understanding the impact of environmental factors on kidney disease and suggest a need for governmental authorities to enhance the monitoring and control of air pollution to mitigate the health burden on the elderly.
