Multielement Composition and in Vitro Bioaccessibility in Brazilian Edible Floral Supplement Capsules Containing Dandelion and Hibiscus.
Article in Biological trace element research, 2026. 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
Dandelion (Taraxacum officinale) and hibiscus (Hibiscus sabdariffa) are notable unconventional edible flowers (UEFs) that have traditionally been used as food and in herbal preparations. This study examined the in vitro bioaccessibility content of six elements (Cr, Cu, Fe, Mn, Ni, and Zn) in edible flower capsules sold in Brazil. Acid digestion in a closed system and microwave-induced plasma optical emission spectrometry (MIP OES) were employed, as well as simulated gastrointestinal digestion according to the INFOGEST 2.0 in vitro protocol. Additionally, we examined the contribution of the in vitro bioaccessible fraction (FBio) in relation to the recommended daily intake (RDI). The concentrations (in µg g⁻
