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
Introduction: Angioedema is a heterogeneous clinical condition characterized by transient swelling of the deeper dermal and submucosal tissues and may occur either in isolation or in association with urticaria. Despite its clinical importance, data regarding clinical phenotypes, triggering factors, and inflammatory laboratory markers in paediatric angioedema remain limited. Aim: This study aimed to retrospectively evaluate the clinical characteristics and laboratory parameters of paediatric patients with angioedema. Material and methods: In this single-centre retrospective study, medical records of paediatric patients aged 0-18 years diagnosed with angioedema between January 2024 and January 2025 were reviewed. Demographic characteristics, angioedema phenotype (isolated angioedema vs. angioedema with urticaria), triggering factors, drug-triggered angioedema, and atopic comorbidities were analysed. Laboratory parameters included hemogram indices, C-reactive protein (CRP), total immunoglobulin E (IgE), complement levels (C3 and C4), and neutrophil-to-lymphocyte ratio (NLR). Appropriate parametric and non-parametric statistical tests were applied. Results: A total of 103 paediatric patients were included. Angioedema accompanied by urticaria was more frequent in females, whereas isolated angioedema predominated in males ( Conclusions: Paediatric angioedema shows distinct clinical phenotypes and laboratory patterns depending on urticaria and triggering factors. Inflammatory markers such as neutrophil counts, CRP, NLR, and basophil levels may help characterize the inflammatory profile of angioedema. Larger multicentre studies are needed to confirm these findings.
