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

backgroundIncomplete miscarriage is a major problem that should be effectively managed with safe and appropriate procedures. Surgical evacuation of the uterus for management of incomplete miscarriage usually involves vacuum aspiration or sharp curettage.

objectivesTo compare the safety and effectiveness of surgical uterine evacuation methods for management of incomplete miscarriage. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (July 2010). SELECTION CRITERIA: Randomized trials where different surgical methods were used to manage incomplete miscarriage were eligible for inclusion. DATA COLLECTION AND ANALYSIS: We extracted population characteristics, settings, and exclusion criteria, in addition to outcomes such as complications of the procedure, duration, need for re-evacuation, blood transfusion, and analgesia/anesthesia. MAIN

resultsTwo trials (involving 550 women) were included. Vacuum aspiration was associated with statistically significantly decreased blood loss (mean difference (MD) -17.10 ml, 95% confidence interval (CI) -24.05 to -10.15 ml), less pain during the procedure (risk ratio (RR) 0.74, 95% CI 0.61 to 0.90), and shorter duration of the procedure (MD -1.20 minutes, 95% CI -1.53 to -0.87 minutes), than sharp metal curettage, in the single study that evaluated these outcomes in 357 women. Serious complications such as uterine perforation and other morbidity were rare and the sample sizes of the trials were not large enough to evaluate small or moderate differences. AUTHORS'

conclusionsAlthough the review indicates that vacuum aspiration is safe, quick to perform, and less painful than sharp curettage, and should be recommended for use in the management of incomplete miscarriage, the results are based on data from only one study. Analgesia and sedation should be provided as necessary for the procedure.
