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

Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with reproductive and metabolic dysfunctions, including gut microbiome dysbiosis. This study aimed to examine the alterations in stemness in ovarian surface epithelium (OSE), gut microbiome microRNA expression in granulosa cells and plasma in a dihydrotestosterone (DHT)-induced rat model of PCOS. Female rats were administered DHT to induce PCOS, and the expression of stem cell markers in OSE was assessed to evaluate the impact on stemness. Alterations in the gut microbiome composition were assessed using 16S rRNA gene Long-Read sequencing and changes in the microRNA profile of granulosa cells and plasma were analyzed using qPCR. Our results demonstrated alterations in stemness markers and, a significant alteration in gut microbiome composition in DHT-induced rats compared to controls, characterized by shifts in the relative abundance of specific bacterial taxa, particularly Akkermansia muciniphila. Elevated levels of miR-574 and miR-378 were observed in plasma, whereas miR-21 and miR-574 showed increased expression in ovarian granulosa cells. Concurrently, increased expression of stem cell markers was observed in OSE, suggesting an enhancement of stemness in response to PCOS-like conditions. These findings imply a potential link between gut microbiome dysbiosis and increased ovarian stemness in PCOS, suggesting that the gut microbiome may contribute to ovarian dysfunction through modulation of stem cell activity. Understanding this interaction could provide novel insights into therapeutic targets in restoring ovarian function in PCOS patients.
