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

objectiveThis study evaluates forceful Foley balloon tugging for 30 s 3-hourly to retrieve a comfortably retained balloon compared to usual care (without tugging) during the 12 h of planned passive placement. The primary outcomes were the induction (Foley insertion) to delivery duration and patients' satisfaction.

methodParticipants were recruited into a randomized controlled trial in a university hospital in Malaysia from March 2023 to December 2023. Nulliparas admitted for induction of labor by Foley balloon were enrolled. After Foley insertion, participants were randomized to 3-hourly tugging or usual care. Following balloon retrieval (whether tugged out, spontaneously expelled, or at scheduled removal), suitability for amniotomy was assessed by vaginal examination. Follow-on labor induction management was guided by the cervical finding.

resultsA total of 264 patients were randomized, with 132 in each study arm. The primary outcomes of induction to birth duration median [interquartile range] was 33.2 [25.3-43.4] versus 37.2 [27.9-45.8] hours (P = 0.058) and participant satisfaction score (0-10 numerical rating scale [NRS]) with the labor induction process was 9 [7-10] versus 9 [7-10] P = 0.437 for tugging versus usual care, respectively. Secondary outcomes with P < 0.05 were Foley removal as planned at 12 h, Foley displacement after tugging, compliance to protocol, and umbilical artery blood pH. However, pH ≤7.10 was 2/126 (1.6%) versus 3/129 (2.3%) relative risk 0.67 95% CI 0.11-3.95 P > 0.99 for tugging vs. usual care.

conclusionAt nulliparous Foley induction of labor with a planned 12-h ballon placement, tugging the Foley 3-hourly compared to usual care did not expedite birth or increase patient satisfaction.
