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
Previous reports suggest an association between the development of atherosclerosis and alterations in the aortic sympathetic nervous system, but there is no agreement on whether atherosclerotic plaques are accompanied by increased or decreased sympathetic innervation in the arterial wall. In the present study, the aortic transcriptional profile of mice with different predisposition to atherosclerosis was investigated to clarify how the expression of genes involved in sympathetic neurotransmission varied. Eight-week-old C57Bl/6J control mice, Apoe knockout mice (EKO), EKO mice overexpressing human apoA-I (EKO/hA-I) and double Apoe/Apoa1 knockout mice (DKO) mice were fed either a standard rodent diet or a Western-type diet for 22 weeks. Atherosclerosis was quantified, and the aortic transcriptome was analyzed by RNAseq. Western-type diet administration deeply modified the aortic transcriptome. In the genetically modified atherosclerosis-prone mouse lines, an upregulated expression of genes associated with the immunomodulatory response was observed, paralleled by a downregulated expression of the genes related to sympathetic nervous system. Functional enrichment analysis indicated that the presence of advanced atherosclerosis was accompanied by reduced neuronal generation, modulation of synapse chemical transmission, and catecholamine biosynthesis, supporting a relationship between atherosclerosis, dyslipidemia, and sympathetic neurotransmission.
