Impact of COVID-19 restrictions on childhood allergic sensitization: a three-phase comparative study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
This study aimed to investigate the influence of COVID-19 restrictions on the prevalence of allergen sensitivity in children. This study included patients who underwent allergen testing at our hospital before deregulation, after deregulation, and during the corresponding period in 2021. Changes in allergen-specific IgE (sIgE) positivity, IgE levels, and polysensitization were analyzed to to evaluate the impact of lifting COVID-19 restrictions on allergic diseases. Compared with those in the prederegulation period and the same period in 2021, the number of children with allergies visiting the hospital decreased following deregulation. The rate of allergen positivity was lower after deregulation than before but higher than that during the same period in 2021. After deregulation, allergen sIgE levels were lower than those before deregulation but higher than those in the same period in 2021. The correlation between milk and beef sensitivity was weaker after deregulation than before but stronger than that in 2021 (R values: 0.814, 0.854, and 0.104, respectively). During the period of COVID-19 restrictions, lower levels of allergic disease activity were observed compared to the pre-deregulation period. However, following the deregulation and the subsequent surge in COVID-19 infections, levels of allergic disease activity appeared to increase relative to the same observation period in 2021.
