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

backgroundCord drainage in the third stage of labour involves unclamping the previously clamped and separated umbilical cord and allowing the blood from the placenta to drain freely into an appropriate receptacle. Currently there are no systematic reviews of the effects of placental cord drainage on the management of the third stage of labour.

objectivesThe objective of this review was to assess the specific effects of placental cord drainage on the third stage of labour, with or without the prophylactic use of oxytocics. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group Trials register (July 2005), CINAHL (1982 to December 2004) and the National Research Register (December 2004). SELECTION CRITERIA: Randomised trials involving placental cord drainage as a variable within the package of interventions as part of the management of the third stage of labour. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the quality of trials and extracted data. MAIN

resultsTwo studies met our inclusion criteria in terms of quality and relevance. Cord drainage could impact the third stage of labour as the results show a statistically significant reduction in the length of third stage of labour (one trial, n = 147, weighted mean difference (minutes) -5.46, 95% confidence interval (CI) -8.02 to -2.90). In the incidence of retained placenta at 30 minutes after birth (one trial, n = 477, relative risk 0.28, 95% CI 0.10 to 0.73) a significant difference was found, but this should be interpreted with caution due to potential intervention bias. AUTHORS'

conclusionsIt is difficult to draw conclusions from such a small number of studies, especially where the review outcomes were presented in a variety of formats. However, there does appear to be some potential benefit from the use of placental cord drainage in terms of reducing the length of the third stage of labour. More research is required to investigate the impact of cord drainage on the management of the third stage of labour.
