In Vitro Fertilization and Dichorionic-Diamniotic Twin Pregnancies in Nulliparous Women: A Retrospective Cohort Study Comparing Pregnancy Outcomes Between Advanced and Younger Maternal Age Groups.

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
Objective: To compare pregnancy outcomes between advanced maternal age (AMA, ≥ 35 years) and younger maternal age (YMA, 20-34 years) nulliparous women with IVF-conceived dichorionic-diamniotic (DCDA) twin pregnancies. Methods: We conducted a retrospective analysis on 141 nulliparous women undergoing cesarean delivery at The Second Nanning People's Hospital (2020-2024). Propensity score matching (PSM, 1:1, caliper width=0.02) was conducted to balanced BMI, gravidity, and menarche age between AMA (n=47) and YMA (n=94) groups. Evaluated parameters included preterm birth (PTB), discordant twin growth, intraoperative blood loss, placental complications (previa/abruption), metabolic disorders (GDM, HDP, ICP), and postpartum hemorrhage (PPH). Results: AMA women had significantly higher rates of discordant twin growth (P<0.05) and greater intraoperative blood loss versus YMA. No significant intergroup differences were observed in PTB, low birth weight, placental complications, GDM, HDP, ICP, or PPH. Conclusion: AMA nulliparous women with IVF DCDA twins face elevated risks of fetal growth discordance and surgical blood loss. However, risks of other maternal-fetal complications align with younger counterparts. Targeted prenatal surveillance for twin growth trajectories and intraoperative hemorrhage management may optimize outcomes in AMA populations. These findings support tailored clinical protocols for this high-risk demographic.
