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 supplement and over-the-counter product use is common among people with a history of cancer and may raise safety concerns, including treatment interactions. We assessed the frequency, patterns, temporal variation and correlates of dietary supplement and over-the-counter product use among adults with a self-reported history of cancer in Poland. PATIENTS AND
methodsWe performed a repeated cross-sectional analysis of six annual waves (2020-2025) of a nationwide quota-based web survey in Poland. Among 1,271,102 respondents overall, 79,588 reported a history of cancer. Dietary supplement and over-the-counter product use in the previous 12 months was assessed by frequency and reported product category or purpose of use. Correlates of any dietary supplement and over-the-counter product use were examined using multivariable logistic regression.
resultsAny dietary supplement and over-the-counter product use was reported by 61.8% of respondents, including daily use in 26.9%, whereas 38.2% reported no use. The most frequently selected categories were multivitamins, digestive products, hair/skin products and sleep products. Men and older respondents had lower odds of dietary supplement and over-the-counter product use, whereas higher education and coexisting non-cancer comorbidities were associated with greater odds of use.
conclusionsDietary supplement and over-the-counter product use was frequently reported among respondents and showed distinct sociodemographic and health-related patterns. Including these products in routine medication histories may help identify potential interactions and other clinically relevant issues.
