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

The objective of this study was to conduct a systematic review and meta-analysis of all randomized controlled trials (RCTs) that evaluated isosorbide mononitrate (ISMN) versus dinoprostone, a prostaglandin E2 (PGE2) analogue, in promoting cervical ripening during labor induction. We searched five major databases from inception till 02 May 2021. We assessed the risk of bias of included studies. We meta-analyzed various endpoints (n=12) and pooled the endpoints as mean difference (MD) or risk ratio (RR) with 95% confidence interval (CI). Overall, 4 RCTs met the inclusion criteria, comprising 818 patients; equally 409 patients were allocated to ISMN and PGE2 groups. Overall, the RCTs had a low risk of bias. The mean change in Bishop score at 24 h was significantly lower in disfavor of the ISMN group. The mean time from drug administration to delivery was significantly longer in disfavor of the ISMN group. The rate of oxytocin need was significantly higher in disfavor of the ISMN group. The rate of vaginal delivery at 24 h was significantly lower in disfavor of the ISMN group. The rates of headache and palpitations were significantly higher in disfavor of the ISMN group. The rate of abnormal fetal heart rate was significantly lower in favor of the ISMN group. There was no significant difference between both groups with regard to rates of cesarean delivery, postpartum hemorrhage, uterine hyperstimulation, and NICU admission. Compared with PGE2, ISMN appeared less effective for cervical ripening prior to labor induction and correlated with higher drug-related maternal toxicities.
