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
ObjectiveMicroRNAs (miRNAs) play a key role in the differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) into chondrocytes. Our previous study found that novel-miR-81 can relieve osteoarthritis, but its role in chondrogenic differentiation of BMSCs remains unclear. The purpose of this study was to explore the role of novel-miR-81 in chondrogenic differentiation of BMSCs.MethodsWe used a model in which transforming growth factor (TGF)-β3-induced BMSCs differentiation into chondrocytes. We detected the expression Sox9, Collagen Ⅱ, Aggrecan, novel-miR-81, and Rac2 by real-time reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Western blot was performed to detect the expression of Sox9, Collagen Ⅱ, and Rac2. Dual-luciferase reporter gene assay confirmed that the association between novel-miR-81 and Rac2. In addition, the ectopic chondrocyte differentiation of BMSCs was performed subcutaneously in nude mice. The effect of novel-miR-81 and Rac2 on ectopic chondrogenic differentiation of BMSCs was determined by immunohistochemical staining.ResultsNovel-miR-81 upregulated in chondrogenic differentiation of BMSCs. Rac2 was a key target of novel-miR-81. Mimic novel-miR-81 and siRac2 upregulated the expression of Sox9, Collagen Ⅱ, and Aggrecan.ConclusionNovel-miR-81 promotes the chondrocytes differentiation of BMSCs by inhibiting the expression of target gene Rac2, which provides potential targets for BMSCs transplantation to repair cartilage defects.
