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
Objective: To understand the prevalence of parent-reported food allergy symptoms among preschool children in Haikou City and investigate indoor environmental risk factors for it. Methods: A cross-sectional survey was conducted with 3,049 preschool children across eight kindergartens in Haikou City from December 2020 to January 2021. The survey aimed to analyze the influence of indoor environmental factors on parent-reported food allergy symptoms in these children. Data collection was facilitated using EpiData 3.1, while SPSS 25.0 was employed for data analysis. The Chi-square ( Results: The prevalence of parent-reported food allergy symptoms in preschool children was 9.25%. Multivariate unconditional logistic regression results suggested that age (odds ratio (OR) = 1.891, 95% confidence interval (CI): 1.246-2.871), nationality other than the Han (OR = 1.753, 95%CI: 1.097-2.802), mother's education level junior college and above than below junior college (OR = 1.395, 95%CI: 1.051-1.851), family allergy history (OR = 2.893, 95%CI: 2.233-3.748), the only child (OR = 1.351, 95%CI: 1.031-1.770), furniture purchased in child's first year (OR = 1.774, 95%CI: 1.263-2.493), mould on surfaces during pregnancy (OR = 1.540, 95%CI: 1.025-2.313), damp exposure during pregnancy (OR = 1.678, 95%CI: 1.120-2.515), exposure to passive smoking (OR = 1.483, 95%CI: 1.143-1.925) were risk factors for parent-reported food allergy symptoms. Conclusion: This study highlights the significant role of the indoor home environment, alongside genetic factors, in the development of parent-reported food allergy symptoms in children. Implementing strategies to reduce indoor moisture and avoid tobacco smoke exposure is essential for preventing parent-reported food allergy symptoms in preschool-aged children.
