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

purposeWe aimed to compare the midterm outcomes of the no-touch saphenous vein graft (NT-SVG) as a second conduit with those of other graft types.

methodsWe retrospectively reviewed 549 consecutive patients who underwent multivessel isolated coronary artery bypass grafting (CABG) with ≥2 distal anastomoses between 2002 and 2024. Five conduit groups for non-LAD grafting were analyzed: in situ internal thoracic artery (ITA), free ITA, conventional saphenous vein graft (cSVG), NT-SVG, and right gastroepiploic artery (rGEA). We analyzed conduit-specific patency and propensity score-matched patency between cSVG and NT-SVG.

resultsThe mean age was 68.6 ± 9.5 years, and 74% were men. Off-pump CABG was performed in 60.5% of cases, with a mean of 3.3 ± 0.9 distal anastomoses. Hospital mortality was 1.5%. Notably, the 5- and 10-year survival rates were 85.9% and 74.1%, respectively. Among 794 non-LAD grafts, the NT-SVG demonstrated a 5-year patency of 96.4%, which was significantly higher than that of cSVG (89.5%, p = 0.05) and rGEA (87.2%, p = 0.04), and equivalent to in situ ITA (94.4%) and free ITA (95.0%). The propensity score-matched analysis further demonstrated superior graft patency with the NT-SVG.

conclusionsThe NT-SVG achieves a 5-year patency comparable to that of ITA grafts and superior to that of cSVG and rGEA, suggesting its potential as a promising option for non-LAD revascularization, pending further validation.
