Association between bilateral radial artery grafting and long-term survival after coronary artery bypass surgery.

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
Objectives: Radial artery (RA) is recommended as a graft for the second most important coronary target after the left internal thoracic artery-to-left anterior descending artery graft. This study assessed the survival benefit associated with bilateral RA use in coronary artery bypass grafting (CABG). Methods: This was a retrospective analysis of prospectively collected data from a binational database including patients who underwent CABG with ≥2 grafts from 2001 to 2020. Patients were stratified into 3 groups: no RA (RA-0), single RA (RA-1), and bilateral RA (RA-2) use. Inverse probability of treatment weighting was used to adjust for baseline differences. The outcome analyzed was long-term all-cause mortality. Results: Of the 59,608 patients included, there were 31,190, 22,741, and 5677 patients in the RA-0, RA-1, and RA-2 groups, respectively. The median postoperative follow-up was 5.0 years (interquartile range, 2.3-8.6 years), with a maximum follow-up of 17.9 years. Compared with RA-0, both RA-1 (hazard ratio [HR], 0.85; 95% CI, 0.81-0.89) and RA-2 (HR, 0.74; 95% CI, 0.67-0.82) were associated with improved survival. RA-2 also demonstrated benefit over RA-1 use (HR, 0.87; 95% CI, 0.79-0.97). Inverse probability of treatment weighting was used to balance comparisons, and the proportional hazards assumption was satisfied ( Conclusions: Bilateral RA grafting was associated with superior long-term survival compared with the use of 1 RA or no RA conduit. Increased adoption of RA conduits in CABG is encouraged, and preservation of both RAs is recommended when CABG is anticipated.
