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 examine the association between decision to delivery interval and maternal and baby outcomes.

designNational cross sectional survey.

settingMaternity units in England and Wales. SUBJECTS REVIEWED: 17 780 singleton births (99% of all births) delivered by emergency caesarean section in England and Wales between 1 May 2000 and 31 July 2000.

main outcome measuresAssociation between decision to delivery interval and baby outcomes (Apgar scores of < 7 and < 4 at five minutes and stillbirth) and maternal outcomes (requirement for special care additional to routine care after caesarean section and where care was provided).

resultsCompared with babies delivered within 15 minutes, there was no difference in maternal or baby outcome for decision to delivery interval between 16 and 75 minutes. After 75 minutes, however, there was a significantly higher odds of a five minute Apgar score of < 7 (odds ratio 1.7, 95% confidence interval 1.2 to 2.4), and 50% increase in odds of special care additional to routine care for mothers.

conclusionA decision to delivery interval of 30 minutes is not an absolute threshold for influencing baby outcome. Decision to delivery intervals of more than 75 minutes are associated with poorer maternal and baby outcomes and should be avoided.
