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
The extracellular matrix (ECM) defines the biomechanical and biochemical microenvironment of tissues, directing cell behaviour and phenotype. In the ovary, ECM must dynamically remodel in each cycle under hormonal regulation to control follicle development and produce fertilizable oocytes. Dysregulation of this process may result in aberrant formation of ECM as seen in polycystic ovary syndrome (PCOS) whose pathology includes fibrosis of the ovary and which is a major cause of infertility. PCOS is characterised by hyperandrogenism and, here, we investigate the impact of androgens on fibrosis, cell-ECM interactions and mechanosensing. We report an altered network of gene expression related to the genesis of fibrosis. Preantral follicles from C57BL/6 mice (14-15 days postpartum) were stimulated with dihydrotestosterone (DHT, 10nM) in 24/72 hours culture. Expression of fibrosis-associated genes (Eln; Ctgf; Acta2; Plod2; Hpse) significantly increased with androgen (72 h), as did TGF-β signalling (Tgfb1; Tgfb3). We show a direct connection between androgen and mechanosensing within the ovary, with androgen upregulating the mechanosensitive Hippo pathway (Yap1; Lats1; Lats2; Stk3; Stk4; Frmd6) and downstream targets (Ctgf; Axl; Cyr61). Our results highlight hyperandrogenism as a probable driver of the fibrosis in the polycystic ovary, and emphasise the importance of ECM regulation in follicle development and fertility.
