Zinc supplementation in pregnancy.
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, 2 of them syntheses 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
backgroundIt has been suggested that low serum zinc levels may be associated with abnormalities of labour, although this has not yet been established.
objectivesThe objective of this review was to assess the effect of zinc supplementation in pregnancy on maternal and fetal mortality and morbidity. SEARCH STRATEGY: The Cochrane Pregnancy and Childbirth Group trials register was searched. SELECTION CRITERIA: Acceptably controlled trials of zinc supplementation in pregnancy. DATA COLLECTION AND ANALYSIS: One reviewer assessed trial quality and extracted data. Study authors were contacted for additional information. MAIN
resultsSeven trials were included. Apart from possible reduction in induction of labour, caesarean section and preterm delivery in the supplemented group, no other differences were detected between groups of women who had zinc supplementation and those who had either placebo or no zinc during pregnancy. REVIEWER'S
conclusionsThere is insufficient evidence to evaluate fully the affect of zinc supplementation during pregnancy. The possible beneficial effects on preterm delivery need to be evaluated in further trials.
