Comparing 3-month and 1-year patency rates of no-touch great saphenous vein and pedicled left internal mammary artery in off-pump coronary artery bypass grafting: a prospective non-inferiority study.

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
Objective: In this study, we compared the 3- and 12-month patency rates of great saphenous vein (GSV) grafts harvested using the no-touch technique and pedicled left internal mammary artery (LIMA) in off-pump coronary artery bypass grafting (OPCABG). We also evaluated the short-term efficacy of the grafts harvested using the no-touch technique. Methods: A non-inferiority study was conducted between June 2019 and August 2022, involving 106 patients who underwent OPCABG using the "no-touch" technique to harvest grafts from the LIMA and GSV. We aimed to assess and compare the patency rates of the pedicled LIMA graft and the no-touch GSV graft at both the 3- and 12-month postoperative intervals. Additionally, we sought to evaluate the advantages of employing the no-touch GSV graft in the context of OPCABG. Results: There was no statistically significant difference in patency between the no-touch GSV graft and the LIMA at 3 and 12 months post-OPCABG ( Conclusion: The no-touch technique can provide graft patency comparability with the LIMA; therefore, in addition to the internal mammary artery, the no-touch GSV is recommended as a graft alternative.
