Air pollution promotes the onset and progression of cardiovascular-kidney-metabolic syndrome: a nationwide prospective cohort study.
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 2 papers.
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
backgroundAir pollution and cardiovascular-kidney-metabolic (CKM) syndrome have emerged as major global public health challenges. However, limited evidence exists on the association between air pollution exposure and CKM incidence and progression.
methodWe analyzed data from participants across CKM stages 0-5 enrolled in the China Health and Retirement Longitudinal Study. Ambient air pollutant concentrations were obtained from the China High Air Pollutants database. Binary logistic regression and weighted quantile sum (WQS) regression models were applied to assess the impacts of individual and combined air pollutants on CKM incidence. Cumulative exposure models were employed to study the long-term effects of pollutants on CKM progression. CKM stages were modeled as ordered categorical outcomes using proportional odds models to examine the association between pollutant levels and CKM progression.
resultsA total of 4,026 individuals were included in the main analysis. Each interquartile range increase in particulate matter with aerodynamic diameters ≤ 1 μm (PM1; OR = 1.008, 95% CI: 1.001-1.015, p < 0.05), ≤ 2.5 μm (PM2.5; OR = 1.009, 95% CI: 1.002-1.015, p < 0.01 ), ≤ 10 μm (PM10; OR = 1.010, 95% CI: 1.004-1.016, p < 0.01), nitrogen dioxide (NO2; OR = 1.011, 95% CI:1.004-1.018, p < 0.01), and ozone (O3; OR = 1.014, 95% CI: 1.006-1.021, p < 0.01) was significantly associated with increased CKM risk. The combined effect of multiple pollutants, reflected by the WQS index, was associated with a 77.7% higher risk of CKM incidence (OR = 1.777, 95% CI: 1.143-2.762, p < 0.05). PM10 (OR = 1.160, 95% CI: 1.059-1.270, p < 0.05) and sulfur dioxide (SO2; OR = 1.122, 95% CI: 1.018-1.236, p < 0.05) were significant contributors to CKM progression. In the cumulative effect analysis of 2,146 individuals, 5-year cumulative PM10 exposure was positively associated with CKM progression (OR = 1.027, 95% CI: 1.001-1.055, p < 0.05).
conclusionAir pollution is a significant environmental determinant of both CKM incidence and progression. Combined and cumulative effects of multiple pollutants may further enhance CKM risk.
