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: FGF19, an endocrine hormone, participating in ovarian function. This study investigated the roles of FGF19 in polycystic ovary syndrome (PCOS) and its associated molecular mechanisms, specifically focusing on the FGFR4-ERK-NRF2 pathway. Methods: Clinical samples were collected to determine FGF19 levels, and proteomic analysis was performed on follicular fluid. A mouse model was established to investigate the molecular pathogenesis of PCOS. Subsequently, a series of Results: Proteomics identified 144 differentially expressed proteins enriched in pathways including VEGF, PPAR, IL-2-STAT5, mTORC1, epithelial-mesenchymal transition, bile acid metabolism, and oxidative phosphorylation. FGF19/FGF15 levels were significantly higher in PCOS patients and mice compared to controls. In PCOS mice, FGFR4, NRF2, and HO1 were upregulated, while p-ERK/ERK levels were decreased. FGF19 overexpression promoted KGN cells viability while inhibiting apoptosis, upregulating FGFR4, NRF2, HO1, BCL2, and p-ERK/ERK, and downregulating BAX. However, LY3214996 reversed the action of FGF19 overexpression in KGN cells. H2O2 treatment decreased KGN cell viability, increased apoptosis, and elevated ROS levels. NRF2 knockdown further aggravated H2O2's effectd, whereas FGF19 overexpression countered the changes in viability, apoptosis, and ROS levels caused by H2O2. Furthermore, H2O2 stimulation upregulated BAX, NRF2, and HO1, while decreasing BCL2 and p-ERK/ERK levels; NRF2 knockdown further upregulated BAX and downregulated BCL2 and p-ERK/ERK. Conversely, FGF19 overexpression had opposite effects on NRF2 knockdown. Conclusion: FGF19 may be involved in PCOS occurrence and development through the regulation of the FGFR4-ERK-NRF2 pathway.
