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

backgroundEclampsia, the occurrence of a convulsion in association with pre-eclampsia, remains a rare but serious complication of pregnancy. A number of different anticonvulsants are used to control eclamptic fits and to prevent further fits.

objectivesThe objective of this review was to assess the effects of magnesium sulphate compared with diazepam when used for the care of women with eclampsia. Magnesium sulphate is compared with phenytoin and with lytic cocktail in other Cochrane reviews. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth trials register (28 November 2002) and the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2002). SELECTION CRITERIA: Randomised trials comparing magnesium sulphate (intravenous or intramuscular administration) with diazepam for women with a clinical diagnosis of eclampsia. DATA COLLECTION AND ANALYSIS: Both reviewers assessed and extracted data. MAIN

resultsSeven trials involving 1441 women are included. Most of the data are from trials of good quality. Magnesium sulphate is associated with a reduction in maternal death when compared to diazepam (six trials 1336 women; relative risk (RR) 0.59, 95% confidence interval (CI) 0.37 to 0.94). There is also a substantial reduction in the risk recurrence of further fits (seven trials 1441 women; RR 0.44, 95% CI 0.34 to 0.57). There were few differences in any other measures of outcome, except for fewer Apgar scores less than seven at five minutes (two trials 597 babies; RR 0.72, 95% CI 0.55 to 0.94) and fewer babies with a length of stay in special care baby unit more than seven days (three trials 631 babies; RR 0.66, 95% CI 0.46 to 0.95) associated with magnesium sulphate. REVIEWER'S

conclusionsMagnesium sulphate appears to be substantially more effective than diazepam for treatment of eclampsia.
