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
backgroundEn bloc resection remains the treatment of choice for primary vertebral column sarcomas but often necessitates total spondylectomy, a procedure associated with high morbidity. The use of patient-specific 3D reconstruction models in combination with intraoperative neuronavigation provides a strategy to achieve oncological resection goals while minimizing resection of uninvolved bone and reducing complication rates. OBSERVATIONS: The authors present 2 cases of thoracic vertebral sarcomas successfully resected en bloc using patient-specific 3D models and intraoperative neuronavigation without performing formal spondylectomy. Postoperative imaging confirmed gross-total resection, and both patients showed durable symptom relief with no evidence of recurrence on follow-up. LESSONS: Integrating 3D modeling and neuronavigation enables tailored en bloc resections of thoracic vertebral sarcomas. This approach preserves structural stability and avoids spondylectomy in select cases, supporting improved oncological and functional outcomes. https://thejns.org/doi/10.3171/CASE25672.
