1 · What the graph read from it

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.

2 · The registry

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 popular among US consumers and claim to address a variety of conditions, including acne. Acne supplements containing vitamin A are of particular interest, due to the potentially teratogenic effects of vitamin A doses over 10,000 IU.

objectiveThis study examined dosage, pregnancy risks, and labeling of vitamin A-containing acne supplements available online.

methodsAn Internet search of acne supplements sold online was conducted between March and May 2020. Supplement labels and websites were analyzed for vitamin A content and pregnancy warnings, and then divided into categories based on dosage and teratogenic risk.

resultsA total of 49 acne supplements was found, and of these 26 (53%) contain vitamin A. Three supplements are likely teratogenic, 4 contain vitamin A doses exceeding the daily level of intake that meets the nutritional needs of most people, and 15 have an unknown teratogenic risk. Among the 6 supplements with over 10,000 IU vitamin A, 2 have no pregnancy warning at all, including the supplement with the highest vitamin A dose found in this study.

conclusionsDietary supplements are not subject to the same stringent regulations as drugs, and as such, consumers may be unaware of pregnancy risks. Furthermore, FDA requirements on labeling of vitamin A supplements may lead to consumer confusion regarding dosage. As such, we encourage stricter labeling requirements for vitamin A-containing supplements, including pregnancy warnings for high-dose supplements and clearer dosage labeling.
