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
backgroundCow's milk is the most frequent cause of food allergies in children, with caseins and β-lactoglobulin being considered the main allergens. Concerningly, numerous international agencies have highlighted a growing risk of allergic reactions in milk-allergic individuals after the consumption of products labelled as "vegan".
objectivesWe describe the case of a 3.5-year-old boy with a history of a food allergy to milk who complained of anaphylactic clinical symptoms after eating a vegan Easter egg. The aim of this study was to confirm the cause of the clinical symptoms, searching for the possible presence of milk proteins in the vegan chocolate.
methodsAn experimental approach based on electrophoretic (SDS-PAGE) and immunoenzymatic techniques (ELISA) was applied.
resultsSDS-PAGE indicated the presence of milk proteins, which was confirmed and quantified via ELISA (3034 ± 115 mg/kg).
conclusionsThe data obtained demonstrate that the severe clinical symptoms were due to the unexpected presence of milk proteins in a vegan product, underlining the critical need for rigorous allergen quality control throughout the food industry.
