Association Between Long-Term Ambient Noise Exposure and Coronary Artery Calcification in a Health Examination Population.

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
objectiveThis study aims to investigate the association between long-term ambient noise exposure and coronary artery calcium (CAC) in a health examination population.
methodsA total of 613 individuals who underwent health examinations between January 2022 and June 2025 were enrolled. Participants were categorized into low-noise (<55 dB), moderate-noise (55-65 dB), and high-noise (≥65 dB) exposure groups. Clinical data were collected. The relationship between noise exposure and CAC was analyzed by using multivariable logistic and linear regression models.
resultsThe CAC detection rate significantly increased with increasing noise exposure levels ( P for trend <0.05). Multivariable linear regression analysis, after full adjustment for potential confounders (Model 3), revealed that compared with the low-exposure group, the moderate- and high-exposure groups had a significantly higher CAC score, with mean increases of 9.85 and 35.27 points, respectively (both P < 0.001). Furthermore, for every 10 dB increase in noise exposure levels, the high-exposure groups had 1.52- and 1.72-fold higher risks, respectively, than the low-exposure group (both P < 0.001). Additionally, for every 10 dB increase in nighttime noise levels, the risk of CAC positivity increased by 17% ( P < 0.001). Subgroup analyses demonstrated that the positive association between noise exposure and the CAC score was more pronounced among males, individuals aged ≥60 years, smokers, and those with hypertension or diabetes (all P for interaction <0.05) than in other patients.
conclusionLong-term ambient noise exposure is independently associated with an elevated CAC score and an increased prevalence of CAC positivity, with nighttime exposure showing a notable association. Specific populations may be highly vulnerable.
