Patterns of Dietary Supplement Use for Weight Loss Among U.S. Adults With Obesity: NHANES 2007-2020.

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
backgroundDietary supplements are commonly marketed for weight loss, yet contemporary national data remain limited on the prevalence of use, types of products used, and whether use is provider-recommended among U.S. adults with obesity.
methodsWe conducted a cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2020. Participants included adults with obesity. They were asked about behaviors on dietary supplements for weight loss. We estimated survey-weighted prevalence overall and by survey cycle, assessed linear trends over time, and used survey-weighted multivariable logistic regression to examine associations with age, sex, race/ethnicity, education, and poverty-income ratio. Among users, we described whether supplement use was recommended by healthcare providers and summarized supplement categories.
resultsAmong 27,116 adults with obesity, 1706 reported using dietary supplements for weight loss. The survey-weighted prevalence of weight-loss supplement use was 5.9% and varied across survey cycles (p for trend = 0.003). Compared with adults aged 20-39 years, odds of use were lower among those aged 40-59 years (adjusted odds ratio [aOR] 0.60, 95% CI 0.45-0.80) and ≥ 60 years (aOR 0.15, 95% CI 0.11-0.22). Females had higher odds of use than males (aOR 1.46, 95% CI 1.13-1.87). Education was positively associated with use, whereas poverty-income ratio was not significantly associated. The use differed by race/ethnicity, with non-Hispanic White adults having lower odds of use compared with Hispanic adults. Among users, 81% reported use without medical advice, and it was more common among males and younger adults. The most frequently used supplements included multivitamin-minerals (28.8%), botanical products (20.0%), and single vitamins (15.2%).
conclusionsApproximately 6% of U.S. adults with obesity reported using dietary supplements for weight loss, most without clinician recommendation and with significant demographic differences. Routine clinical assessment of supplement use and counseling regarding limited efficacy and potential safety concerns are warranted.
