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
Female infertility diseases such as polycystic ovary syndrome (PCOS), endometriosis, diminished ovarian reserve (DOR), and recurrent implantation failure (RIF) have different clinical phenotypes. However, they might be epigenetically convergent, and thus the therapeutic targets may be potential. This study utilized transcriptome data, microRNA (miRNA), and DNA methylation data from the granulosa cells of four Gene Expression Omnibus (GEO) datasets, GSE138518, GSE105765, GSE232306, and GSE92324, to conduct integrated bioinformatics analysis. We focused on differentially expressed genes (DEGs), constructed a miRNA-mRNA network, performed ROC curve analysis, and conducted function enrichment and drug repurposing studies. Our findings identified eight dysregulated genes (H19, SULT1A4, HCK, SPI1, CARD16, NFE2, LST1, and KRT8) common to PCOS, DOR, and RIF, which may serve to distinguish PCOS specifically. Moreover, these DEGs are associated with pathways such as innate immune activation, inflammatory responses, the NOD-like receptor signaling pathway, and Fc gamma R-mediated phagocytosis. Notably, MiRNAs differentially expressed in endometriosis (specifically hsa-miR-202-5p and hsa-miR-141-3p) were found to directly target this gene set, highlighting the role of epigenetic regulation across infertility diseases. Additionally, our drug repurposing analysis identified several FDA-approved drugs, including Abacavir and Peginterferon Alfa-2b, suggesting that the HCK gene may be a viable target for drug development to address female infertility. Furthermore, we identified 192 genes that correlated with DNA methylation and expression levels in PCOS. Thus, this study underscores the epigenetic convergence of different female infertility diseases and highlights potential biomarkers and therapeutic options that could enhance treatment in reproductive medicine.
