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

introductionThe appropriate mode of delivery for breech babies is a topic of ongoing debate. After the publication of the Term Breech Trial in 2000, the proportion of breech babies delivered vaginally in Sweden rapidly dropped to 7% from 26%. In 2015, international guidelines changed to once again recommend offering vaginal breech deliveries in select cases. In 2017, a Swedish hospital established a dedicated Breech Team to provide safe vaginal breech deliveries according to the new guidelines. The aim of this study is to compare neonatal morbidity in the group planned for cesarean breech delivery with the group planned for vaginal breech delivery treated in accordance with the new guidelines. The study adds to the literature by providing insights into the consequences of reintroducing vaginal breech births in a high-resource health-care setting. MATERIAL AND

methodsA prospective observational study was conducted at Södersjukhuset's maternity ward with 1067 women who gave birth to a single breech fetus at term. Outcomes were compared between the planned vaginal and planned cesarean delivery groups using intention-to-treat analysis and multivariate analysis to control for confounders.

resultsOut of the 1067 women, 78.9% were planned for cesarean delivery and 21.1% were planned for vaginal delivery. The planned vaginal group had a significantly greater risk for neonatal morbidity compared to the planned cesarean group (3.1% vs. 0.7%; OR 4.44, 95% CI 1.48-13.34). The risk difference remained significant after controlling for confounders.

conclusionsPlanned vaginal breech delivery was associated with an increased risk of neonatal mortality and short-term morbidity compared to planned cesarean breech delivery in accordance with the new guidelines. The potential risks and benefits of planned vaginal breech delivery should be carefully weighed against those of planned cesarean delivery.
