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

objectiveTo evaluate the risk of recurrence of adverse perinatal outcomes in second pregnancies in developing countries.

methodsData from the 2004-2008 Global Survey on Maternal and Perinatal Health were used to determine the outcomes of singleton second pregnancies for 61 780 women in 23 developing countries. The mother-infant pairs had been followed up until discharge or for 7 days postpartum.

findingsAt the end of their second pregnancies, women whose first pregnancy had ended in stillbirth (n = 1261) or been followed by neonatal death (n = 1052) were more likely than women who had not experienced either outcome to have given birth to a child with a birth weight of < 1500 g (odds ratio, OR: 2.52 and 2.78, respectively) or 1500-2499 g (OR: 1.22 and 1.60, respectively), or to an infant requiring admission to an intensive care unit (OR: 1.64 and 1.68, respectively). At the end of their second pregnancies, those whose first pregnancy had ended in a stillbirth were at increased risk of another stillbirth (OR: 2.35) and those whose first infant had died as a neonate were at increased risk of having the second infant die within the first 7 days of life (OR: 2.82). These trends were found to be largely unaffected by the continent in which the women lived.

conclusionIn the developing world, a woman whose first pregnancy ends in stillbirth or is followed by the death of the neonate is at increased risk of experiencing the same outcomes in her second pregnancy.
