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

purposeTo determine whether there is an association between term cesarean breech delivery in the first pregnancy and maternal and neonatal morbidities in the subsequent pregnancy and delivery.

methodsWe conducted a retrospective, nationwide Finnish population-based cohort study, including all deliveries from January 2000 to December 2017. We included all women with the first two consecutive singleton deliveries of which the first one was a breech delivery regardless of mode of delivery (n = 11,953), and constructed a data set in which the first two deliveries for these women were connected. The outcomes of the second delivery of the women with a first pregnancy that resulted in cesarean breech delivery at term were compared with women whose first pregnancy resulted in a vaginal breech delivery at term. P-value, odds ratio, and adjusted odds ratio were calculated.

resultsNeonates of a subsequent delivery after cesarean breech delivery had an increased risk for arterial umbilical cord pH below seven, a higher rate of a 5 min APGAR score < 7 and a higher rate of neonatal intensive care unit admission. The women with a history of cesarean section with the fetus in breech presentation were more often in need of a blood transfusion and suffered more often a uterus rupture. In this group, the second delivery was more often a planned cesarean section, an emergency cesarean section, or an instrumental vaginal delivery.

conclusionsPrimary cesarean breech section in the first pregnancy is associated with adverse neonatal and maternal outcomes in the subsequent delivery.
