Comparing pre- and post-COVID-19 chronic allergy prevalence in children using National Health and Nutrition Examination Survey in 2019 and 2021.
Review in Allergologie select, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 investigate changes in demographic characteristics, parental smoking habits, and the prevalence of asthma, atopic dermatitis, and rhinitis among children in South Korea before and after the COVID-19 pandemic. MATERIALS AND
methodsA retrospective analysis of national health survey data from 2019 and 2021 was conducted, including children aged 3 - 18 years. Factors such as gender, age, location, housing type, family size, income, body mass index, subjective health status, influenza vaccination, family structure, and parental smoking habits were analyzed.
resultsNo significant differences were found in most demographic characteristics and parental features between 2019 and 2021, except for influenza vaccination rates and mothers' age at first childbirth. The influenza vaccination rate increased from 69.3% in 2019 to 77.8% in 2021, and the average maternal age at first birth increased from 28.46 years to 29.22 years. Asthma diagnoses showed no significant differences between the 2 years after adjusting for general and parent-related characteristics. For atopic dermatitis, significant differences in gender distribution were observed in 2021. Rhinitis diagnoses showed significant differences in age, area, and breastfeeding status between the two years.
conclusionThe COVID-19 pandemic may have influenced certain demographic characteristics, such as influenza vaccination rates and mothers' age at first childbirth, but the prevalence of asthma, atopic dermatitis, and rhinitis among children remained largely unchanged between 2019 and 2021. This study underscores the importance of monitoring the impact of social changes on children's health, particularly during significant events like the COVID-19 pandemic. Further research is required to understand the long-term effects of these changes on child health.
