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

backgroundEgg allergy is one of the most common food allergies in early childhood and is traditionally managed through strict avoidance diets, which may negatively affect nutrition and quality of life. Early oral immunotherapy (OIT) may represent an alternative therapeutic strategy; however, controlled studies in children younger than two years remain limited.

methodsWe conducted a prospective observational study using historical controls. Thirty-one children younger than two years with IgE-mediated egg allergy underwent OIT using pasteurized liquid egg white (maximum dose: 30 mL; 3300 mg protein). Twelve children managed with an avoidance diet served as the historical control group. Outcomes included desensitization rates, adverse reactions, and longitudinal changes in skin prick test (SPT) wheal diameters, serum-specific IgE (sIgE), specific IgG4 (sIgG4), and sIgE/total IgE ratios.

resultsAt six months, 29/31 children (93.5%) in the OIT group did not experience allergic reactions after ingestion of any egg preparation, compared with none in the historical control group (

conclusionsEarly OIT with pasteurized egg white in children younger than two years with IgE-mediated egg allergy was associated with high desensitization rates, favorable short-term safety outcomes, and significant immunological changes. These findings support the potential role of early active intervention as an alternative to exclusive avoidance strategies in infants with egg allergy.
