Surgeon Experience and Outcomes: Specific, Analogy-Based and Cumulative Learning in Cardiac Surgery.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2026. 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
objectivesTo assess how different learning mechanisms, including specific learning, analogy-based learning, and cumulative experience, influence surgical outcomes following coronary artery bypass graft (CABG), aortic valve replacement (AVR), and mitral valve reconstruction (MVR) surgeries.
methodsBetween 2010 and 2023, 46 surgeons performed 21 269 cardiac surgeries (CABG, AVR, and MVR) at a major heart surgery centre in Germany. Surgical proficiency was assessed using the 30-day risk-adjusted mortality rate (RAMR) and risk-adjusted re-thoracotomy rate (RARR), calculated for each surgeon and adjusted using EuroSCORE II. Linear regression models examined associations between learning mechanisms and surgical outcomes.
resultsHigher procedure-specific volume in the preceding quarter was significantly associated with a lower 30-day RAMR for CABG, demonstrating a decline of 0.49 percentage points (95% CI, -0.88 to -0.10; P = .014). Furthermore, analogy-based learning demonstrated a significant cross-procedural effect for CABG, as prior-quarter volumes of technically related procedures (AVR and MVR) exhibited significant non-linear associations with 30-day RAMR. For MVR, greater cumulative experience significantly reduced the RARR (-0.295; 95% CI, -0.55 to -0.03; P = .028). No significant volume-outcome associations were observed for AVR.This analysis included 21 269 total procedures (12 706 CABG, 5477 AVR, and 3086 MVR) from 2010 to 2023. Surgeons had a mean specialist experience of 8.2 years (CABG), 10.3 years (AVR), and 11.9 years (MVR) and performed a mean of 12, 5.1, and 5.1 procedure-specific surgeries per quarter, respectively.
conclusionsMaintaining consistent, procedure-specific practice and accumulating experience are crucial for improving cardiac surgery outcomes.
