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
backgroundEmerging evidence suggests that specific allergen molecules may influence the clinical phenotype of anaphylaxis in children, but robust data are scarce. This study aimed to rigorously test the molecule-phenotype association in a large pediatric cohort and to determine the relative influence of the sensitizing molecule versus patient age on symptom presentation.
methodsA retrospective analysis was conducted on 184 pediatric patients (0-18 years) hospitalized for anaphylaxis. Molecular allergen-specific immunoglobulin E (IgE) profiles were determined using the ALEX
resultsThe most frequent molecular triggers were Ara h 2 (18.79%), Gal d 1 (9.09%), and Ana o 3 (9.09%). While significant differences in symptom distribution were observed within individual allergen molecules (p < 0.05), no molecule-specific symptom pattern was identified. In contrast, age significantly influenced respiratory symptom prevalence, with a higher frequency in older children compared to infants (p = 0.003). A similar trend was observed for gastrointestinal symptoms (p = 0.051).
conclusionsIn pediatric anaphylaxis, patient age is a more significant determinant of clinical presentation, particularly for respiratory symptoms, than the specific sensitizing allergen molecule. This suggests that clinical risk stratification and management strategies in children should prioritize age-related factors over specific molecular sensitization profiles.
