Cold Waves and Elevation Strengthen the Association of Particulate Matter Exposure With Hypertension Prevalence: A Large Multiregional Study in China.

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
backgroundHypertension is a major global health burden. While air pollution is a known risk factor, the interactive effects of co-occurring stressors like cold weather and geographic elevation are poorly understood. This study investigated the independent and joint effects of long-term particulate matter (PM) exposure, cold waves, and elevation on hypertension.
methodsWe conducted a cross-sectional study of 27 602 adults across multiple regions in China. Long-term exposures to PM and its chemical components were estimated using 3 independent, high-resolution data sets, alongside cumulative cold-wave days and residential elevation. Generalized linear models and principal component analysis were used to estimate associations with hypertension prevalence and blood pressure, assessing both multiplicative and additive interactions.
resultsLong-term exposure to PM with a diameter of ≤2.5 μm was significantly associated with higher odds of hypertension (odds ratio per 10 μg/m
conclusionsThe association between air pollution and hypertension is significantly modified by local climatic and geographic conditions. The synergistic effect of PM and cold waves suggests current assessments may underestimate the burden in susceptible regions, necessitating integrated, climate-informed public health strategies.
