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

objectiveThis study aimed to investigate the prevalence, major allergens, and associated risk factors of food allergy (FA) among children under three years old in Guangdong, China.

methodsA community-based cross-sectional study was conducted in 2023 across three cities (Guangzhou, Foshan, Huizhou) representing varying urbanization levels. Using multistage stratified cluster sampling, 745 children aged 0-35 months were included. Data were collected via caregiver questionnaires and with physician verification when available.

resultsThe overall prevalence of FA was 6.8%, with higher rates observed in urban Guangzhou (9.0%) compared to Foshan (6.5%) and Huizhou (5.0%). Milk (3.1%) and egg (2.1%) were the most common allergens, followed by aquatic products (1.9%). Cutaneous symptoms, particularly rash (60.6%) and pruritus (39.3%), predominated.

conclusionFA is a significant health concern among infants in Guangdong, with distinct allergen profiles and urban-rural disparities. These findings underscore the need for region-specific dietary guidance and individualized infant feeding practices to mitigate allergy risk and address nutritional concerns in allergic children.
