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

Exosomal microRNAs (ex-miRs), encapsulated in extracellular vesicles (EVs), play a vital role in facilitating paracrine communication among granulosa cells (GCs), cumulus cells (CCs), and the oocyte inside follicular fluid (FF). These small non-coding RNAs are crucial for regulating folliculogenesis, oocyte maturation, and early embryonic development via modulating intracellular signaling networks. Dysregulation o has been associated with reproductive disorders such as polycystic ovarian syndrome (PCOS), diminished ovarian reserve (DOR), and inadequate ovarian response (POR), impacting oocyte quality and fertility outcomes. This narrative review consolidates molecular data from current human and animal studies regarding ex-miR expression patterns, functional targets, and pathway involvement within the context of assisted reproductive technologies (ARTs). A literature-based analysis was undertaken, focusing on signaling pathways, pathogenic processes, and clinical implications. Specifically, ex-miRs-such as miR-21, miR-34c, miR-143-3p, miR-155-5p, miR-339-5p, and miR-424-5p-were identified as regulators of critical pathways including phosphoinositide 3-kinase (PI3K)-AKT, ERK1/2, TGF-β/SMAD, and Rb-E2F1. These ex-miRs regulate apoptosis, glycolysis, mitochondrial function, and cell cycle expansion to influence oocyte competence. Pathological patterns in PCOS and POR are associated with altered ex-miR expression that disrupts metabolic and developmental signaling. Research utilizing animal models confirmed that modifications in EV-associated miRNA influence in vitro maturation (IVM) efficiency and blastocyst quality. Ex-miRs serve as intriguing non-invasive biomarkers and potential therapeutic targets for ARTs. Their mechanical involvement in oocyte and follicular physiology positions them for integration into forthcoming precision-based infertility therapies. For its implementation in reproductive medicine, EV profiling requires standardization and further functional validation in clinical environments.
