1 · What the graph read from it

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.

2 · The registry

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

objectivesRobot-assisted mitral valve replacement has been shown to be comparable to conventional surgery in terms of safety and efficacy. Our institution has performed robot-assisted mitral valve replacement using the Da Vinci Surgical System for over a decade. This study aimed to evaluate the time-related evolution of clinical outcomes and the impact of the surgical learning curve.

methodsPatients who underwent robot-assisted mitral valve replacement between July 2013 and January 2024 were evaluated. All procedures were performed by 4 surgeons certified in robotic cardiac surgery, each with prior experience of more than 100 conventional mitral valve replacements. To assess the learning curve, cumulative sum analysis was conducted on cardiopulmonary bypass time and the Mitral Surgery Complexity Score.

resultsA total of 233 patients were included in the analysis. The mean patient age was 48.4 (13.9) years; 117 (50.2%) were male. The mean cardiopulmonary bypass time was 170.3 (55.1) min. Cumulative sum analysis of cardiopulmonary bypass time revealed 3 phases: a learning phase (cases 1-27), a proficiency phase (cases 28-92), and a mastery phase (cases 93 onward). Mitral Surgery Complexity Scores decreased during the early phase, followed by an increase after case 92, indicating a transition towards more complex cases.

conclusionsRobot-assisted mitral valve replacement has a measurable learning curve, with surgical efficiency and case complexity evolving over time. Approximately 93 procedures appear necessary to achieve operative stability and to confidently expand indications to include more complex patients.
