Evaluation of maternal and neonatal complications in preeclamptic twin versus singleton pregnancies: a retrospective study.
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
purposeThis study aims to compare maternal and neonatal outcomes in singleton and twin pregnancies complicated by preeclampsia, emphasizing differences between preterm and term deliveries.
methodsThis is a retrospective study conducted at "Virgen de la Arrixaca" University Hospital (Murcia, Spain), from 2009 to 2020. Maternal demographic data and maternal and neonatal outcomes were collected from hospital records. Pregnancies were stratified by delivery before and after 37 weeks of gestation.
resultsThe study included 161 singleton pregnancies and 77 twin pregnancies, all complicated by preeclampsia. Preterm delivery rates (< 37 weeks) were significantly higher in twin compared to singletons (79.2% vs. 48.4%). The mean maternal hospital stay was longer in twins (9.0 days) than for singletons (7.6 days). Maternal complications occurred in 13.7% of singleton pregnancies and 28.6% of twin pregnancies (p = 0.006), with maternal hemorrhage more frequent in twins (22.1% vs. 9.3%; p = 0.007). Maternal complications were more common in twin pregnancies (OR = 3.13; 95%CI 1.38-7.10). Cesarean delivery (OR = 2.00; 95%CI 0.85-4.66) and BMI (OR = 0.96; 95%CI 0.90-1.03) were not associated with the maternal composite outcome. Neonatal complications occurred in 29.2% of singleton pregnancies and 30.0% of first twin and 27.3% of second twin (p = 0.890 and 0.790 respectively). Factors associated with neonatal complications included birthweight (OR 0.99; 95%CI 0.99-0.99) and delivery between 34 and 37 weeks of gestation (OR = 0.08; 95%CI 0.01-0.59) and delivery after 37 weeks of gestation (OR = 0.04; 95%CI 0.01-0.46).
conclusionsMaternal complications were more frequent in twin pregnancies complicated by preeclampsia, while neoantal complications were more likely to occur in cases of preterm preeclampsia.
