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

backgroundAdministering antenatal corticosteroids (ACS) to those at risk for early-preterm delivery has been widely recommended, yet the evidence regarding twin pregnancies remains insufficient and controversial.

methodsThis 8-year retrospective cohort study analyzed twin pregnancies at risk for early preterm birth (24 + 0 to 33 + 6 weeks of gestation) in a university-affiliated hospital in China from 2013 to 2020. Propensity score overlap weighting was used to analyze the association between ACS administration and the risk of neonatal outcomes. The primary outcome was the composite neonatal respiratory morbidity, defined as at least one of the following: postnatal occurrences respiratory distress syndrome, mechanical ventilation, surfactant administration, transferred with respiratory complications, or neonatal death.

resultsThe study population consisted of 277 individuals with twin pregnancies, including 221 (79.8%) who received corticosteroids during 24 + 0 to 33 + 6 weeks of gestation as ACS group, and 56 (20.2%) who did not as no-ACS group. The propensity score overlap weighting showed no significant differences in the risk of neonatal primary outcome (161 [72.9%] vs. 40 [71.4%], weighted OR, 1.07[95% CI, 0.40-2.91]) between the two groups. None of the subgroup interaction tests were significant for the neonatal primary outcome in terms of year of delivery, advanced maternal age, parity, assisted reproductive technology, gestational diabetes mellitus, hypertensive disorders in pregnancy, gestational age at delivery, mode of delivery, chorionicity, intertwin growth discordance and infant sex, and neither was the sensitive analysis of using propensity score matching, different administration-to-birth interval, and treating twin infants as individuals.

conclusionIn this retrospective cohort study, no significant association was observed between ACS administration during the early-preterm period in twin pregnancies and a decreased risk of newborn morbidity. Further research is necessary to determine whether the same ACS regimen for twin pregnancies should be recommended in the real world as it is for singletons.
