Supplement Safety Knowledge, Information Sources, and Self-Reported Safety-Related Behaviors Among Adults Aged 40 Years and Older: A Pilot Study.

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
BACKGROUND/
objectivesDietary supplement use is common in middle and later adulthood, but factual safety knowledge may not necessarily translate into safety-related behavior. This pilot study examined supplement use, supplement safety knowledge, information-source pathways, and self-reported safety-related behaviors among adults aged 40 years and older.
methodsA cross-sectional questionnaire study was conducted in Poland between December 2025 and April 2026 in a convenience sample of 150 adults aged ≥40 years. Multivariable logistic regression models assessed associations of a five-item factual supplement safety knowledge score and professional or digital information-source use with proactive supplement safety information seeking and other supplementation behaviors.
resultsCurrent supplement use was reported by 113/150 participants (75.3%); among current users with available supplement count data, 86/111 (77.5%) used at least two supplements simultaneously. The knowledge score was not independently associated with proactive supplement safety information seeking (aOR 0.93 per one-point increase, 95% CI 0.69-1.25;
conclusionsIn this convenience sample, the study-specific factual knowledge score did not show a clear independent association with proactive supplement safety information seeking. Associations involving professional information sources depended partly on outcome definition, while the association with lower self-initiation remained. Given the pilot nature, modest sample size, non-probability recruitment, self-reported measures, and lack of product-level verification, the findings are hypothesis-generating and require confirmation in larger, prospectively characterized samples.
