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

objectivesTo compare the Optimality Index of planned birth in a birth centre with planned birth in a hospital and planned home birth for low-risk term pregnant women who start labour under the responsibility of a community midwife.

designProspective cohort study.

settingLow-risk pregnant women under care of a community midwife and living in a region with one of the 21 participating Dutch birth centres or in a region with the possibility for midwife-led hospital birth. Home birth was commonly available in all regions included in the study.

participants3455 low-risk term pregnant women (1686 nulliparous and 1769 multiparous) who gave birth between 1 July 2013 and 31 December 2013: 1668 planned birth centre births, 701 planned midwife-led hospital births and 1086 planned home births. MAIN OUTCOME MEASUREMENTS: The Optimality IndexNL-2015, a tool to measure 'maximum outcome with minimal intervention', was assessed by planned place of birth being a birth centre, a hospital setting or at home. Also, a composite maternal and perinatal adverse outcome score was calculated for the different planned places of birth.

resultsThere were no differences in Optimality Index NL-2015 for pregnant women who planned to give birth in a birth centre compared with women who planned to give birth in a hospital. Although effect sizes were small, women who planned to give birth at home had a higher Optimality Index NL-2015 than women who planned to give birth in a birth centre. The differences were larger for multiparous than for nulliparous women.

conclusionThe Optimality Index NL-2015 for women with planned birth centre births was comparable with planned midwife-led hospital births. Women with planned home births had a higher Optimality Index NL-2015, that is, a higher sum score of evidence-based items with an optimal value than women with planned birth centre births.
