Polyphenol-rich tea decreases iron absorption from fortified wheat bread in Senegalese mother-child pairs and bioavailability of ferrous fumarate is sharply lower in children.
Trial report in European journal of clinical nutrition, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 1 of them a synthesis that pooled 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.
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.
Who cites it
12 citing papers in PubMed, 1 synthesis or guideline pooled it, 25 citations in OpenAlex.

Abstract
BACKGROUND/
objectivesFractional iron absorption (FAFe) from ferrous fumarate (FeFum) and ferrous sulfate (FeSO
methodsSenegalese mother-child pairs (n = 17) were randomly assigned to receive, in a 2 × 2 factorial design, fortified bread with
resultsIn children, relative bioavailability (RBV) from FeFum was 51 and 64% compared with FeSO
conclusionsIn Senegalese women and children, herbal tea decreased FAFe from a wheat-based meal. The RBV of FeFum was low in children but not in their mothers. FAFe was modestly correlated in mother-child pairs, possibly due to shared genetic, epigenetic or environmental background.
