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
Long non-coding RNAs (lncRNAs), which are RNA molecules longer than 200 nucleotides that do not encode proteins, are implicated in a variety of biological processes, including growth and development. Despite research into the role of lncRNAs in skeletal muscle development, the regulatory mechanisms governing ovine skeletal muscle development remain unclear. In this study, we analyzed the expression profiles of lncRNAs in skeletal muscle from 90-day-old embryos (F90), 1-month-old lambs (L30), and 3-year-old adult sheep (A3Y) using RNA sequencing. In total, 4 738 lncRNAs were identified, including 997 that were differentially expressed. Short-time series expression miner analysis identified eight significant expression profiles and a subset of lncRNAs potentially involved in muscle development. Kyoto Encyclopedia of Genes and Genomes enrichment analysis revealed that the predicted target genes of these lncRNAs were primarily enriched in pathways associated with muscle development, such as the cAMP and Wnt signaling pathways. Notably, the expression of lncRNA GTL2 was found to decrease during muscle development. Moreover, GTL2 was highly expressed during the differentiation of skeletal muscle satellite cells (SCs) and was shown to modulate ovine myogenesis by affecting the phosphorylation levels of PKA and CREB. Additionally, GTL2 was found to regulate both the proliferation and differentiation of SCs via the PKA-CREB signaling pathway. Overall, this study provides a valuable resource and offers novel insights into the functional roles and regulatory mechanisms of lncRNAs in ovine skeletal muscle growth and development.
