Outpatient cervical ripening with Foley balloon or mifepristone: Insights into the time taken to reach the active phase of labor.

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.
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 estimate the median time elapsed between the start of cervical ripening and the diagnosis of the active phase of labor, according to maternal and pregnancy characteristics, in low-risk pregnancies submitted to outpatient cervical ripening with a Foley balloon catheter or oral mifepristone.
methodsThis was a secondary analysis of a randomized controlled trial conducted in a European tertiary level hospital, including 101 women with singleton pregnancies, cephalic presentation, and an unfavorable Bishop score. Participants were randomized to receive an intracervical Foley balloon catheter or oral mifepristone (200 mg). The main outcome evaluated was the median time elapsed between the start of the cervical ripening process and the active phase of labor. Cox proportional hazards regression was used to estimate hazard ratios (HR) for factors influencing progression to active labor.
resultsThe median interval from the start of cervical ripening to the active phase of labor was 34.3 h (interquartile range [IQR]: 25-50.1). Previous pregnancy (HR: 1.74; 95% CI: 1.18-2.58), gestational age (HR: 1.34; 95% CI: 1.04-1.73), and a permeable cervix at baseline (HR: 2.28; 95% CI: 1.44-3.63) were significantly associated with progression to the active phase of labor. Foley balloon and mifepristone showed comparable median times to the active phase of labor, whereas much shorter durations were observed in those with a permeable cervix at baseline.
conclusionMaternal age, gestational age, parity, and permeable cervix at baseline significantly influence the time interval from the start of cervical ripening to the active phase of labor. These may constitute a useful set of information for individualized patient counseling, allowing better alignment of expectations and increased satisfaction with the induction process.
