Global trends and insights in fetal fibronectin and preterm delivery research: A comprehensive bibliometric analysis based on data-driven studies

Objective: To assess the global trends and insights in fetal fibronectin (fFN) and preterm delivery based on data-driven studies. Methodology: The study utilized bibliometrics to analyze global trends in fFN and Preterm Delivery Research (FFPDR), identifying key contributors, notable publications, and new hotspots. Scopus was used as the primary database, and a systematic data extraction process was employed to identify original Scopus-indexed publications. Results: The highly impactful FFPDR focuses on the predictive accuracy of fFN testing for spontaneous preterm birth, its integration with transvaginal cervical length measurements, its use in high-risk and symptomatic populations, and its role in guiding clinical interventions. Key trends include diagnostic advancements, predictive models, and collaborative networks, which shape the research landscape. Conclusion: This study highlights global FFPDR trends; identifies key contributors; and emphasizes diagnostic advancements, predictive models, and collaborative research networks.
