Inter-twin delivery interval and outcome of the second twin: A retrospective study.

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 examine the association between the inter-twin delivery interval and outcome of the second twin in a large sample.
methodsThis was a retrospective study at a single tertiary center between the years 2011 and 2021. The study included diamniotic twin pregnancies at ≥24 weeks of gestation that underwent a trial of vaginal delivery. A total of 1808 cases of twin pregnancies were included in the study. Cases were grouped according to inter-twin delivery interval of ≤15 min (n = 1676) or >15 min (n = 132). The neonatal outcome of the second twin was compared between the groups. In addition, we evaluated possible factors affecting the inter-twin delivery interval.
resultsUmbilical cord pH and base deficit were significantly lower and higher, respectively, for the second twin in the prolonged interval group; however, no difference was shown concerning neonatal composite outcome. In addition, a prolonged inter-twin interval was significantly associated with maternal age, body mass index, gestational age, labor induction, rupture of membranes duration, intrapartum fever, nighttime shift, birth weight of the second twin, twin birth weight ratio, and discordancy >20%. On the other hand, a short inter-twin interval was significantly associated with monochorionicity and neonatal intensive care unit admission.
conclusionsOur study showed no significant effect of inter-twin delivery interval on the composite outcome of the second twin. However, a prolonged inter-twin interval was associated with lower umbilical cord pH and higher base deficit.
