Association between gallstones and subclinical coronary atherosclerosis: An observational study with propensity score matching.
Observational study in PloS one, 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
Previous studies reporting an association between gallstones and coronary artery disease have not considered the types of coronary artery plaque. Additionally, the association between gallstones and subclinical coronary atherosclerosis has not been clearly elucidated. Therefore, this study aimed to analyze the association between gallstones and subclinical coronary atherosclerosis based on the type of coronary artery plaque in asymptomatic Koreans using coronary computed tomography angiography. We retrospectively analyzed 9,113 individuals (mean age, 53.7 ± 8.0 years; 5,907 men [64.8%]) who had no history of coronary artery disease and underwent a general medical checkup. Gallstones were diagnosed by transabdominal ultrasonography. Coronary computed tomographic angiography was used to evaluate the type of coronary artery plaque and the severity of subclinical coronary atherosclerosis, and a diameter stenosis of ≥50% was considered clinically significant. Logistic regression and propensity score matching analyses were performed to determine the association between gallstones and subclinical coronary atherosclerosis. Among the study participants, 503 (5.5%) had gallstones. After adjusting for risk factors, significant associations were found between gallstones and noncalcified plaque (adjusted odds ratio [OR], 1.728; 95% confidence interval [CI] 1.267-2.357; p = 0.001), as well as between gallstones and significant coronary artery stenosis (adjusted OR, 1.386; 95% CI, 1.002-1.917; p = 0.049). In asymptomatic individuals, gallstones were independently associated with noncalcified plaque (the high-risk plaque) and significant coronary artery stenosis which is often linked to poorer cardiac outcomes. It is crucial to acknowledge the potential for subclinical coronary atherosclerosis and to effectively manage cardiovascular risk factors in individuals with gallstones.
