Twin delivery: does induction of labor make a difference?
Article in Archives of gynecology and obstetrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeInduction of labor as well as delivery in twin pregnancies bears specific risks. The goal of this study was to analyze the delivery mode in twin pregnancies and influence of induction on the cesarean delivery (CD) rate and perinatal outcome and to identify risk factors for CD and an intertwin interval ≥ 15 min.
methodsThis single-center retrospective cohort study analyzed the outcome of 267 twin pregnancies. Inclusion criteria for vaginal delivery in twins are gestational age (GA) > 34 weeks, leading twin in cephalic presentation, estimated weight difference ≤ 500 g and no previous uterine surgery. Women were divided into three groups: 1 = vaginal delivery, 2 = CD for both twins, 3 = emergency CD for second twin. Outcomes were mode of delivery, and influence of induction on the CD rate.
resultsWe had 156 women (58%) in group 1, 97 (36%) in 2 and 14 (5%) in 3. Induction of labor was performed in 147 cases and led to a higher CD rate (23% vs. 47%, p < 0.001). Induction of labor and nulliparity were associated with a higher risk for CD for both twins. Risk factors for an intertwin interval of ≥ 15 min were maternal age and weight of the second twin. An intertwin interval of ≥ 15 min was associated with a lower umbilical artery pH in the second twin.
conclusionThe rate of CD doubled if induction of labor was necessary. These results emphasize on careful patient counseling that includes information about the risks of deliveries in twin pregnancies.
