Effects of fetal presentation on mode of delivery in 26 143 twin pregnancies: A nationwide, population-based observational study of 31-year real-world data.

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 describe the rate of combinations of fetal lies and presentations in twin pregnancies at delivery and to assess the effects of fetal lies and presentations on mode of delivery as well as fetal and maternal birth outcomes.
methodsThis population-based cohort study used real-world data from the Medical Birth Registry of Norway and included all twin births (n = 26 143) in Norway during 1988-2018. Logistic Regression Analysis was Applied. Main outcome measures were planned and actual modes of delivery categorized into vaginal deliveries and cesarean sections. Secondary outcomes were postpartum hemorrhage and intrapartum stillbirth.
resultsMost twin births were planned as vaginal deliveries (83.4%, 21 811/26 143), of which (65.9%, 14 371/21 811) were successful. Vaginal delivery was more often successful in parous than in nulliparous women, or if the first or both twins were in cephalic presentation compared with non-cephalic presentation of the first or both twins. Planned cesarean section was more likely to be chosen if the first or both twins were in non-cephalic presentation than if they were in cephalic presentation. Maternal parity, demographic and obstetric risk factors had little or no effect on the association between twin presentations and planned or actual delivery mode.
conclusionsMore than half of women with a twin pregnancy had a successful vaginal delivery. Keeping the option of the vaginal route as the primary mode of delivery in a twin pregnancy maintains the right of the woman to have a vaginal delivery and avoid a uterine scar.
