Coronary artery bypass grafting using both internal mammary arteries-a safe concept for surgical training.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesIn our centre, a bilateral internal mammary artery first approach is established from day 1 of surgical training. We herein aimed to investigate safety and clinical efficacy of this training concept.
methodsAll patients undergoing isolated bypass grafting between 2009 and 2021 at our institution were included in this study. Patients provided with single mammary artery, radial artery or vein grafts were excluded. According to a preoperative evaluation conducted by experienced coronary bypass surgeons, coronary artery disease severity was classified, and patients were allocated to group 1 (surgery performed by staff surgeons) and group 2 (surgery performed by residents under supervision of staff surgeons). Thirty-day outcome parameters were compared between groups.
resultsA total of 2125 patients were allocated to group 1, and 431 patients were assigned to group 2. Patients in group 1 presented a higher risk profile. Coronary artery bypass grafting in group 2 was more often performed as on-pump procedure with a longer procedure duration. Number of performed bypasses was lower in group 2 with fewer composite grafting and fewer anastomoses to the RCA territory. No significant differences in 30-day all-cause mortality, myocardial infarction, stroke or acute kidney injury were seen.
conclusionsThirty-day outcomes after coronary artery bypass grafting using bilateral internal mammary artery grafts performed by residents were without significant differences to outcomes of staff surgeons, suggesting that application of both internal mammary arteries by residents is safe and effective when performed under supervision and after preoperative patient screening.
