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
objectiveTo analyze gene expression profiles analysis during the differentiation of sheep muscle-derived stem cells (MDSCs) into smooth muscle cells (SMCs) in sheep.
methodsA modified preplate technique was employed to isolation of the MDSCs from sheep. The MDSCs were subjected to flow cytometry analysis targeting CD44, CD31, CD45, CD14, and CD49f and were treated with TGF-β1 at a concentration of 10 ng/ml for ten days. The expression levels of smooth muscle α-actin (α-SMA) and calponin after treatment with TGF-β1 were determined by western blotting and immunofluorescence staining. A microarray analysis was performed to screen for differentially expressed genes (DEGs) during MDSC differentiation using total RNA extracted from MDSCs and SMCs generated from MDSCs. Molecule Annotation System (MAS) 3.0, which employs KEGG (Kyoto Encyclopedia of Genes and Genomes) and GO (Gene Ontology) Consortium annotations, was used to identify global biological trends in the gene expression data.
resultsThe expression levels of the SMC-specific contractile proteins α-SMA and calponin were dramatically increased after treatment with TGF-β1. Immunofluorescece staining showed that the TGF-β1-treated MDSCs were positive for α-SMA. We identified 486 genes that were differentially expressed between the MDSCs and TGF-β1-treated MDSCs. 260 of which were up-regulated and 226 of which were down-regulated. Twenty-one genes exhibited a greater than ten-fold change, 13 of which were up-regulated and 8 of which were down-regulated. TGF-β1 treatment up-regulated both the SMAD and MAPK signaling pathways during the differentiation of these sheep cells. The PPAR and Wnt signaling pathways were also found to be involved in the differentiation process.
conclusionsTGF-β1 can successfully induce the differentiation of sheep MDSCs into SMCs. For the first time, we analyzed the gene expression profiles associated with this differentiation process, and the results showed that both the SMAD and MAPK signaling pathways are involved. This study indicated that multiple signaling networks coordinate the development and differentiation of MDSCs into SMCs.
