Trial report in International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 6 papers, 2 of them syntheses that pooled it.

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 compare the efficacy and safety of the hourly administration of titrated oral misoprostol solution (OMS) and vaginal dinoprostone for induction of labor.

methodsTitrated OMS was administrated hourly for induction of labor, starting with a dose of 20 µg and terminating at a dose of 50 µg. The safety and efficacy of OMS were compared with that of vaginal dinoprostone for induction of labor.

resultsFrom June 2016 to October 2019, 2280 (78.3%) and 2115 (72.9%) women who received titrated OMS and vaginal dinoprostone, respectively, had a vaginal delivery (P = 0.005). Cesarean delivery was performed in 632 (21.7%) and 783 (27.0%) women who received titrated OMS and vaginal dinoprostone, respectively (P = 0.008). Tachysystole with changes in fetal heart rate (FHR) was seen in 104 (3.6%) and 249 (8.6%) women in the OMS and dinoprostone groups, respectively (P = 0.007). The frequency of non-reassuring FHR was lower in the OMS group compared to the dinoprostone group (P = 0.006).

conclusionThe titrated OMS has an efficacy comparable to vaginal dinoprostone. Moreover, it causes a lower incidence of cesarean delivery, lower frequency of tachysystole with changes in FHR, and non-reassuring FHR.
