Association between oxidative balance score and gallstone risk and gallbladder surgery: A cross-sectional study.
Article in The Journal of international medical research, 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
ObjectiveTo examine the association between oxidative balance score and the risks of gallstones and gallbladder surgery in US adults, addressing the lack of reliable oxidative stress-related indicators for gallstone prediction.MethodsA cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey 2017-2020. Multivariate logistic regression, subgroup analyses, and smoothed curve fitting models were applied to investigate the relationship between oxidative balance scores and gallstone outcomes, adjusting for age, sex, race, and health conditions.ResultsHigher oxidative balance score was significantly associated with lower risks of gallstones and gallbladder surgery. Each 1-unit increase in the oxidative balance score corresponded to a 2.6% reduction in gallstone risk (odds ratio = 0.974; 95% confidence interval: 0.958, 0.990) and a 3.3% reduction in gallbladder surgery risk (odds ratio = 0.967; 95% confidence interval: 0.950, 0.983). Subgroup and dose-response analyses confirmed these consistent, negative associations.ConclusionsHigher oxidative balance score is independently associated with a reduced prevalence of gallstones and gallbladder surgery. Furthermore, maintaining a higher antioxidant status may play a role in the management of gallstone disease risk.
