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

Background: Polycystic Ovary Syndrome (PCOS) is among the most prevalent endocrine disorders in women of reproductive age and may significantly impact pregnancy outcomes. However, no comprehensive bibliometric analysis has synthesized research findings in this field. Objective: This study aims to identify trends and key research areas in PCOS and pregnancy outcomes and to summarize effective treatment strategies for PCOS-related infertility. Method: Literature was retrieved and collated from the Web of Science Core Collection (WOSCC) and PubMed databases up to 10 May 2025. Bibliometric analysis was conducted using VOSviewer, CiteSpace, and R software. Result: A total of 410 WOSCC publications and 45 PubMed clinical trials were included. China ( Conclusion: This first bibliometric analysis of PCOS and pregnancy outcomes provides a comprehensive overview of the research landscape. Future research should focus on insulin resistance mechanisms, metabolic syndrome management, and the optimization of assisted reproductive technologies including frozen embryo transfer, letrozole combination therapies, and traditional Chinese medicine approaches.
