1 · What the graph read from it

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.

2 · The registry

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

objectivesOne possible reason for the long-term patency of no-touch (NT) saphenous vein grafts (SVG) is the preservation of the vasa vasorum in the adventitia/perivascular adipose tissue (PAT). We investigated the vasa vasorum of the NT SVG in vivo using frequency-domain optical coherence tomography (FD-OCT), performed qualitative and quantitative analyses and compared them with the conventional SVG.

methodsAn FD-OCT study was performed on 14 SVG at the postoperative coronary angiography 1-2 weeks postoperatively (NT group, n = 9; conventional group, n = 5).

resultsMany signal-poor tubular lumen structures that can be recognized in the cross-sectional and longitudinal profiles, which indicates the vasa vasorum, were observed in the adventitial/PAT layer in the NT SVG. In contrast, the vasa vasorum were less abundant in the conventional SVG. The volume of vasa vasorum per millimetre of graft in the no-touch group was significantly higher than in the conventional group [0.0020 (0.0017, 0.0043) mm3 and 0.0003 (0.0000, 0.0006) mm3, P = 0.023].

conclusionsFD-OCT showed abundant vasa vasorum in the thick adventitia/PAT layer of NT saphenous veins in vivo. In contrast, few vasa vasorum were observed in the conventional SVG.
