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
Background: This study applied a skill decomposition approach to identify and quantify technical nuances of performing subtasks of a microvascular anastomosis by analyzing suturing maneuvers, the duration of each step, and technical insufficiencies in a controlled setting. Methods: Four microneurosurgery trainees performed 16 end-to-side microanastomoses, alternating between the interrupted technique (IT) and the continuous technique (CT) of suturing on standardized artificial vessels. At the subtask level, 24 reproducible suturing techniques and 42 technical insufficiencies were identified and analyzed. Results: Significant contributors to faster suture included biting both walls in a single move, dominant-hand suturing, and suturing directed toward the participant. Total anastomosis time correlated negatively with the sequential attempt order ( Conclusion: By converting well-known microsurgical concepts into measurable performance subtasks, the skill decomposition approach offers a foundation for objective skill assessment and targeted training intervention. Identified maneuvers and insufficiencies that influenced the anastomosis subtasks form the foundation for evidence-based microsurgery training. A better understanding of the most effective microsurgical suturing techniques will contribute to their refinement, improving anastomosis quality and decreasing performance time.
