Characterising the allergen landscape in paediatric allergic rhinitis and/or asthma.
Article in BMJ open respiratory research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo characterise the allergen sensitisation profile and its demographic, seasonal and laboratory associations in children with allergic rhinitis (AR) and/or asthma in Guangdong, China.
methodsWe retrospectively reviewed the records of children diagnosed with AR and/or asthma from January 2020 to December 2023. Serum allergen-specific Immunoglobulin E (IgE) measurements were used to identify allergens. Sensitisation patterns and their relationships with age, sex, season of visit, peripheral-blood cell counts and immune markers were assessed with χ² tests and Spearman correlation.
resultsA total of 8080 children (median age, 7.0 years; 69.0% boys) were included; 89.1% had AR, 7.5% asthma and 3.4% both conditions. Overall, 76.5% were sensitised to inhalant allergens, 18.3% to food allergens and 5.2% to other allergens. Dermatophagoides farinae (93.2 %) and Dermatophagoides pteronyssinus (88.3 %) were the dominant inhalant allergens, whereas egg (14.2 %) and milk (11.9 %) prevailed among foods. Dual sensitisation was most common (67.6 %). Inhalant sensitisation peaked in summer (79.8 %), whereas food sensitisation was highest in spring (6.8 %). Inhalant-allergen positivity increased with age, while food-allergen positivity declined (p<0.001). Seventeen of 18 allergens displayed significant sex differences. Total IgE correlated positively with most inhalant and food allergens but negatively with egg allergen (p<0.05); neutrophil percentage showed similar positive correlations with several allergens. Allergen sensitisation correlates with impaired lung function and elevated airway inflammation.
conclusionHouse-dust mites are the principal sensitising allergens in children with AR and/or asthma in Guangdong, followed by egg and milk. Sensitisation patterns are modulated by season, age and sex, underscoring the necessity for region- and age-specific preventive and therapeutic strategies in paediatric allergic disease management.
