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
Bone marrow-derived mesenchymal stem cells (MSC) are a potential attractive source of cells for stem cell-based tissue regeneration, but the small number and reduced capabilities of MSC proliferation and differentiation due to in vitro replicative senescence and donor-associated pathophysiological factors, including age and estrogen depletion, severely restrict their potential usefulness in clinical applications. Glucocorticoids (GC) are well-known steroid hormones that regulate MSC proliferation and differentiation, but the defined effects and underlying mechanisms of endogenous glucocorticoids on MSC characteristics are not understood. This study investigated the effects of the blockage of endogenous GC using glucocorticoid receptor (GR) small interfering RNA (siRNA) delivered using biodegradable poly(lactic-co-glycolic acid) (PLGA) microparticles on proliferation and differentiation capabilities of human MSC in vitro. The results show that we can prepare PLGA microparticles as a delivery system for GR siRNA and maintain release of siRNA up to 40 days in vitro. Transfection of GR siRNA significantly downregulates GR and upregulates the expression of fibroblast growth factor-2 and Sox-11 of human MSC. MSC that have proliferated with endogenous GC blocked in vitro have greater proliferation rates and exhibit upregulated expression of osteogenic markers (alkaline phosphatase and core binding factor alpha 1) under differentiation stimulation after 1 week. Under adipogenic differentiation, MSC proliferated in vitro with siRNA transfection, resulting in significantly lower adipogenic markers (peroxisome proliferator-activated receptor and lipoprotein lipase) than controls. In conclusion, PLGA particles can serve as a tool for delivery of GR siRNA to effectively block the effects of endogenous GC on MSC, which has the potential to improve the capabilities of human MSC for clinical application by preventing replicative senescence.
