Jugular Vein Injection of High-Titer Lentiviral Vectors Does Not Transduce the Aorta-Brief Report.
Article in Arteriosclerosis, thrombosis, and vascular biology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
objectiveEfficient gene transfer to the vascular wall via intravenous vector injection would be useful for experimental vascular biology and gene therapy. Initial studies of lentiviral vector tropism suggested that intravenously injected vectors do not transduce murine vascular tissue; however, there are also reports of highly efficient aortic transduction after jugular vein injection of high-titer lentiviral vectors. We sought to reproduce these results. Approach and Results: We injected high-titer preparations of GFP (green fluorescent protein)-expressing lentiviral vector into jugular veins of 8 mice; 6 mice received vehicle only. Four days later, samples of aorta (thoracic and abdominal), liver, spleen, and other tissues were harvested and processed for quantitative polymerase chain reaction detection of vector DNA and immunohistochemical detection of GFP. Our vector DNA assay did not detect transduction of any of the 16 aortic segments. This finding excludes an aortic transduction efficiency of >0.02 vector copies per cell. In contrast, vector DNA was detected in all 8 spleen and liver extracts (median, 0.8 and 0.1 vector copies per cell, respectively;
conclusionsInjection of high-titer lentiviral vectors via the jugular vein transduces cells in the spleen and liver but does not efficiently transduce the aorta. Graphic Abstract: A graphic abstract is available for this article.
