Association between dietary niacin intake and the odds of gallstones in US adults: A cross-sectional study in NHANES 2017-2020.
Article in Preventive medicine reports, 2025. 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
Objective: To investigate the association between dietary niacin intake and the risk of gallstones in American adults using data from the National Health and Nutrition Examination Survey (NHANES) from 2017 to 2020. Methods: This cross-sectional study analyzed data from 8191 participants aged 18 years and older. Dietary niacin intake was assessed using two 24-h dietary recalls. The presence of gallstones was identified through a questionnaire. Logistic regression models were used to estimate odds ratios (ORs) and 95 % confidence intervals (CIs) for gallstones across quartiles of niacin intake, adjusting for demographic and health-related covariates. Results: Participants with higher niacin intake showed a significantly lower risk of gallstones. After adjusting for a wide range of covariates, individuals in the highest quartile of niacin intake had a 49 % reduced risk of gallstones compared to those in the lowest quartile (OR = 0.51, 95 % CI: 0.34, 0.76). Conclusion: Higher dietary niacin intake is associated with a reduced risk of gallstones in US adults. These findings suggest that increasing niacin intake could be a viable strategy for the prevention of gallstones. Future longitudinal studies are needed to confirm these results and explore the underlying mechanisms.
