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

objectiveTo determine whether vaginal application of 40 mg isosorbide-5-mononitrate (ISMN) has a comparable cervical ripening efficacy to and lesser side effects than 400 µg misoprostol in women scheduled for the first trimester induced abortion using a manual vacuum aspirator (MVA).

methodsWe conducted a prospective randomized open-label study in 70 women at 6-12 weeks of pregnancy at the R G Kar Medical College and Hospital, Kolkata, India, over a period of two years from 2015 to 2017. Forty milligrams of ISMN and 400 µg misoprostol were vaginally applied for cervical priming. The primary outcome measure was the cervical response assessed by the passage of the appropriate and largest sized MVA cannula through the internal os without resistance, at the beginning of the procedure.

resultsThe base line cervical dilatation was found to be significantly higher in the misoprostol group than in the ISMN group (7.65±1.38 vs. 6.9±1.26 mm;

conclusionIn the primigravid women, misoprostol appears to exert a higher efficacy as a cervical ripening agent in contrast to ISMN. However, ISMN can be used in multigravid women for the same purpose as in this group, misoprostol did not show any significant improvement in efficacy over ISMN.
