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

The association between cesarean delivery and childhood allergic diseases, such as atopic dermatitis, food allergy, and bronchial asthma, remains unclear, with limited evidence from Asian populations. We analyzed population-based data of 2,114 children born in Japan in 2010 from the Longitudinal Survey of Babies in the 21st Century, linked to the Perinatal Research Network Database. Comparisons were made between children born by cesarean delivery and those born vaginally. Longitudinal outcomes were atopic dermatitis, food allergy, and bronchial asthma during childhood for each age group up to 9 years of age. We performed Poisson regression analyses with robust variance, and adjusted for child and parent variables, followed by supplementary analyses using generalized estimating equations (GEE). Children born by cesarean delivery did not have a higher risk of most outcomes compared to those born vaginally. GEE analysis found no association between cesarean delivery and atopic dermatitis (adjusted risk ratio [aRR] 0.8, 95% confidence interval [CI] 0.5-1.2), food allergy (aRR 1.1, 95% CI 0.7-1.7), bronchial asthma (aRR 1.0, 95% CI 0.8-1.4), or allergic rhinoconjunctivitis (aRR 0.9, 95% CI 0.8-1.1). This study shows no clear evidence of an association between delivery mode and childhood allergic diseases in Japan.
