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
backgroundMesenchymal stem cells (MSCs) were able to restore ovarian function in premature ovarian insufficiency (POI), which can be largely attributed to the paracrine effects of MSCs therapy. However, the function and mechanism of MSC-derived exosomes transplantation for POI are not fully understood.
objectivesTo investigate the efficacy and underlying mechanisms of human placental derived MSCs derived exosomes (hpMSC-Exos) xenotransplantation in incremental load training-induced POI.
methodThe incremental exercise treadmill training was employed for constructing the POI rat model. hpMSC-Exos were administered to POI rats by tail vein injection. The ovarian function was assessed based on histological analysis and hormone levels. Ovarian function parameters, follicle counts, oocyte aging, granulosa cell apoptosis, and follicular microenvironment were evaluated.
resultsThe tracking of hpMSC-Exos indicated that they generally colonized the ovarian tissues. hpMSC-Exos transplantation increased telomere length and telomerase activity, reduced oxidative stress, downregulated the Bax and caspase-3 gene expression, upregulated the Bcl-2 gene expression, and increased the insulin-like growth factor 1 (Igf-1) and vascular endothelial growth factor (VEGF) expression level. Furthermore, the findings showed that the follicle-stimulating hormone (FSH) level and FSH to luteinizing hormone (LH) ratio were decreased, whereas the population of follicles significantly increased after transplantation.
conclusionhpMSC-Exos transplantation was observed to improve the function of the injured ovarian tissues in the incremental load training-induced POI rats. Furthermore, the mechanisms of hpMSC-Exos are related to delaying aging in the oocyte, reducing apoptosis of granulosa cells, and regulating the follicular microenvironment.
