Comparative Analysis Perinatal Complications Among Women with ART-Induced Pregnancy and Natural Conception.
Article in International journal of women's health, 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
Objective: This study conducted a retrospective matched analysis to explore the differences and potential associations in perinatal complications between pregnancies achieved through in-vitro fertilization-embryo transfer (IVF-ET) and natural conception. Methods: A total of 806 pregnant women who delivered at the Department of Obstetrics, First Hospital of Lanzhou University, China, from January 2019 to August 2024 were included, with 403 cases in the experimental group and 403 matched controls (natural conception) based on admission month and gestational age (±7 days). Results: Analysis revealed that the experimental group exhibited significantly higher incidences of multiple gestations, anemia, postpartum hemorrhage, gestational hypertension, gestational diabetes mellitus, and intrahepatic cholestasis of pregnancy compared to the control group. In singleton pregnancy analysis, these differences persisted except for pelvic inflammation. The findings suggest that ART pregnancies may increase perinatal risks through factors such as embryo manipulation, hormonal interventions, and underlying maternal pathologies. Conclusion: This matched retrospective study highlights that IVF-ET pregnancies are associated with significantly higher risks of multiple gestations and obstetric complications, independent of multifetal pregnancies. The findings underscore the necessity of optimizing embryo transfer strategies, such as promoting single embryo transfer and implementing enhanced monitoring protocols for high-risk complications in resource-limited settings like Northwest China. This study provides regional evidence to support the development of tailored ART guidelines.
