External cephalic version for breech presentation before term.
Synthesis in The Cochrane database of systematic reviews, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundManagement of breech presentation is controversial, both in regard to manipulation of the position of the fetus and the method of delivery. External cephalic version may reduce the number of breech presentations and caesarean sections, but there also have been reports of increased perinatal mortality with the procedure.
objectivesThe objective of this review was to assess the effects of external cephalic version for breech presentation before term on measures of pregnancy outcome. SEARCH STRATEGY: The Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Controlled Trials Register were searched. Date of last search: October 1997. SELECTION CRITERIA: Randomised and quasi-randomised trials of external cephalic version before term (37 weeks gestation) compared with a control group in women with breech presentation before term. DATA COLLECTION AND ANALYSIS: Eligibility and trial quality were assessed by the reviewer. MAIN
resultsThree studies involving 889 women were included. There was no significant effect of external cephalic version before term on the following: non-cephalic presentation (relative risk 1.02, 95% confidence interval 0.89 to 1.17); caesarean section (relative risk 1.10, 95% confidence interval 0.78 to 1.54); low Apgar scores (relative risk 0.81, 95% confidence interval 0.44 to 1.49); perinatal mortality (relative risk 1.19, 95% confidence interval 0.46 to 3.05). REVIEWER'S
conclusionsExternal cephalic version before term does not appear to improve pregnancy outcomes.
