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 condition causing histopathological alterations in the ovarian stroma. Telocytes (TCs) are specialized interstitial/stromal cells present in the connective tissue of various organs. In this study, we investigated the presence and spatial organization of TCs in the ovaries of a rat model of PCOS induced by dehydroepiandrosterone (DHEA). The ovarian tissues from both PCOS and control groups were stained using hematoxylin-eosin (H&E), Bielschowsky's silver stain, methylene blue, and toluidine blue for light microscopy analysis, and scanned digitally. Ovaries were marked with double-labeled immunofluorescence with CD34/estrogen receptor-α (ER-α) and vimentin/progesterone receptor-A (PR-A) and evaluated with a confocal microscope. The ultrastructure and telopodes (TPs) of TCs were also examined by transmission electron microscopy. TCs were identified in both groups, localized within follicular walls, adjacent to follicles, in stromal regions distant from the follicles, and perivascular areas. CD34/ER-α and vimentin/PR-A cells were significantly increased in PCOS. In conclusion, TCs were preserved in the DHEA-induced PCOS model, and according to our quantitative analysis, their ultrastructural features were unaffected by the PCOS microenvironment. Our findings suggest a potential association between TCs and the pathophysiology of PCOS. Further studies are necessary to elucidate the functional relationship of TCs in the development and progression of PCOS.
