Long-term weight change patterns in American adulthood in relation to gallstones: evidence from NHANES.
Article in BMC gastroenterology, 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
backgroundThe aim of this study is to investigate the association between weight change patterns across adulthood and gallstones in the United States.
methodsThe analysis is based on data from participants aged 40-70 years taken from the National Health and Nutrition Examination Survey 2017-2020. Weight status and weight change patterns were categorized based on body mass index at three time points. Weighted logistic regression was used to estimate the association of weight status at the three time points and weight change patterns over the three periods with gallstones.
resultCompared with normal weight, obese status at age 25 was associated with an 86% increased risk of gallstones (OR 1.86, 95%CI 1.07-3.24). No significant associations were observed for underweight or overweight status. Weight status at baseline or 10 years before baseline showed no relation to gallstones. Notably, the stable obese pattern from age 25 to baseline was positively associated with gallstones (OR 1.94, 95%CI 1.03-3.65). A similar association was observed from age 25 to 10 years before baseline (OR 1.92, 95%CI 1.05-3.49). However, weight change patterns from 10 years before baseline to baseline were not significantly associated with gallstone risk. Subgroup analyses revealed stronger associations among females, diabetic individuals, and those with low physical activity.
conclusionThe stable obese pattern starting from early adulthood is associated with an increased risk of gallstones in Americans. Preventing or controlling obesity in early adulthood may be helpful in the primary prevention of gallstones.
