Bilateral internal thoracic artery grafting in isolated coronary artery bypass grafting: A 35-year experience.
Article in JTCVS open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: The study objectives were to analyze trends in bilateral internal thoracic artery grafting during isolated coronary artery bypass grafting over a 35-year interval and compare outcomes between bilateral internal thoracic artery and non-bilateral internal thoracic artery strategies. Methods: A cohort of 15,991 patients underwent isolated multivessel coronary artery bypass grafting at our institution between 1990 and 2024. Trends in bilateral internal thoracic artery, radial artery, and left internal thoracic artery + saphenous vein graft were assessed using chi-square tests with Bonferroni correction. Changes in obesity and diabetes prevalence across intervals were also analyzed. Propensity score matching (1:1) yielded 2013 pairs for outcome comparisons between bilateral internal thoracic artery and non-bilateral internal thoracic artery groups. Results: Between 1990 and 2024, use of bilateral internal thoracic artery and radial artery increased (11.0% and 13.2%, respectively), although bilateral internal thoracic artery declined during 2020 to 2024 as radial artery and left internal thoracic artery + saphenous vein graft use increased. This decline was unrelated to rising obesity or diabetes rates. Matched analysis revealed longer operative times for bilateral internal thoracic artery (+51 minutes, Conclusions: Bilateral internal thoracic artery grafting remains underused, particularly in recent years, despite demonstrated survival benefits and comparable wound-healing risks. The decline is not explained by patient risk factors, highlighting the need for broader adoption of bilateral internal thoracic artery grafting and further randomized trials to optimize coronary artery bypass grafting strategies.
