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

introductionSeveral studies indicate that delivery by caesarean section may be one of the risk factors for the development of childhood asthma.

aimA meta-analysis was carried out to establish the relationship between delivery by caesarean section and asthma in children. MATERIAL AND

methodsAfter a review of bibliographic databases, 41 articles were obtained and 12 of which were accepted for further analysis. The odds ratios (OR) included in the analysis were specified on the basis of data from the presented studies or were calculated using reported prevalence. The analysis took into account unadjusted OR. The heterogeneity of results was assessed using the χ

resultsCaesarean delivery was associated with an increased risk of development of childhood asthma (OR = 1.41); however, significant heterogeneity of results was demonstrated. A significantly higher risk of asthma was found in children born by caesarean section in the case where the disease was confirmed in a questionnaire-based study (OR = 1.26, 95% CI: 1.05-1.5), and the results of that study were homogeneous.

conclusionsIn the case of the diagnosis of asthma declared by parents in the questionnaire-based study, a significantly higher risk of disease occurrence was observed in children born by caesarean section. Due to the significant heterogeneity of the results of the studies, it cannot be clearly stated that caesarean delivery is a risk factor for the development of bronchial asthma.
