No-touch versus conventional vein in coronary artery bypass grafting: three year follow-up of multicentre randomised PATENCY trial.
Trial report in BMJ (Clinical research ed.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to trial NCT03126409 (A Multicenter Randomized Trial to Compare the Graft Patency Between No-Touch Vein Harvesting Technique and Conventional Approach in Coronary Artery Bypass Graft Surgery), which is not on this map. Cited by 10 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.

Abstract
objectiveTo assess the three year outcomes of the no-touch vein harvesting technique in coronary artery bypass grafting surgery compared with the conventional approach.
designThree year extended follow-up of the randomised PATENCY (graft patency between the no-touch vein harvesting technique and conventional approach in coronary artery bypass graft surgery) trial.
settingSeven cardiac surgery centres in China; enrolment between April 2017 and June 2019.
participants2655 participants aged 18 and older undergoing isolated coronary artery bypass grafting surgery.
interventionsPatients were randomly assigned 1:1 to the no-touch vein harvesting technique group or the conventional approach group during surgery and followed up.
main outcome measuresVein graft occlusion (based on computed tomography angiography) at three years.
resultsMean age of participants was 61 years (standard deviation ±8 years) and 22% were women. 99.4% (2621) attended the three year follow-up visit, while 86.5% (2281) received computed tomography angiography. At three years, the no-touch group showed a significantly lower vein graft occlusion rate (5.7%
conclusionsThe no-touch technique consistently and robustly reduced the risk of vein graft occlusion and several cardiac events by one third to one half within three years after coronary artery bypass grafting surgery.
