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 investigate possible differences in operative delivery rate among low-risk women, randomised to an alongside midwifery-led unit or to standard obstetric units within the same hospital.

designRandomised controlled trial.

settingDepartment of Obstetrics and Gynaecology, Østfold Hospital Trust, Tromsø, Norway. POPULATION: A total of 1111 women assessed to be at low risk at onset of spontaneous labour.

methodsRandomisation into one of three birth units: the special unit; the normal unit; or the midwife-led unit.

main outcome measuresTotal operative delivery rate, augmentation, pain relief, postpartum haemorrhage, sphincter injuries and intrapartum transfer, Apgar score <7 at 5 minutes, metabolic acidosis and transfer to neonatal intensive care unit.

resultsThere were no significant differences in total operative deliveries between the three units: 16.3% in the midwife-led unit; 18.0% in the normal unit; and 18.8% in the special unit. There were no significant differences in postpartum haemorrhage, sphincter injuries or in neonatal outcomes. There were statistically significant differences in augmentation (midwife-led unit versus normal unit RR 0.73, 95% CI 0.59-0.89; midwife-led unit versus special unit RR 0.69, 95% CI 0.56-0.86), in epidural analgesia (midwife-led unit versus normal unit RR 0.68, 95% CI 0.52-0.90; midwife-led unit versus special unit RR 0.64, 95% CI 0.47-0.86) and in acupuncture (midwife-led unit versus normal unit RR 1.45, 95% CI 1.25-1.69; midwife-led unit versus special unit RR 1.45, 95% CI 1.22-1.73).

conclusionsThe level of birth care does not significantly affect the rate of operative deliveries in low-risk women without any expressed preference for level of birth care.
