Heavy metal exposures in aerodigestive clinic cohort of infants with reflux or dysphagia.
Article in Scientific reports, 2025. 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
Infant cereals (rice/oatmeal), purees, and anti-reflux formulas are often first line treatments for thickening in infants with reflux and oropharyngeal dysphagia. However, there has been growing concern about heavy metal contamination, especially arsenic, in these commonly used thickeners. This is a particular concern in infants who may be more susceptible to heavy metal neurotoxicity. The study aimed to assess whether there are differences in heavy metal levels, particularly arsenic, in infants with reflux or oropharyngeal dysphagia while on different thickeners. We performed a single center study in infants (< 1 year of age) with diagnosis of reflux or oropharyngeal dysphagia who were seen between December 2021-2023. Participants submitted urine samples and completed dietary questionnaires to assess their elemental exposures. The primary outcome of interest was urinary arsenic concentrations, though other elements were also measured. Of the 56 infants, 27 were on gelmix
