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
purposeThe spine is a primary site for metastases; While only 10% of malignant tumors develop symptomatic spinal metastases, these cases significantly impair quality of life. En-Bloc Spondylectomy (EBS) is a rarely employed but potentially curative surgical option for patients with favorable prognoses. This study evaluates the clinical presentation, surgical procedures, outcomes, and complications associated with EBS in patients with spinal metastasis.
methodsThis retrospective series included 40 consecutive patients who underwent EBS for spinal metastases between June 2010 and October 2021. Clinical characteristics, treatments, complications, recurrence rates, and survival outcomes were analyzed.
resultsThoracic spine metastases accounted for 80% of cases. The most common histologies were clear cell carcinoma of the kidney and follicular thyroid tumor. Wide margins were achieved in 38% of cases, marginal in 17%, and intralesional in 45%. The average blood loss was 1665 ml, and surgeries averaged 7.5 h.Early complications occurred in 32.5% of patients, with neurological deterioration being the most frequent. The 5-year local recurrence-free survival (LRFS) rate was 64.0%, and the 5-year overall survival (OS) rate was 34.5%. DISCUSSION: Despite significant technical challenges, EBS offers a viable treatment option for select patients with spinal metastases, particularly in cases of radioresistant histologies. Achieving oncologically adequate margins and careful preoperative planning are crucial for successful outcomes.
conclusionEBS represents a complex but feasible surgical option that may provide durable local control in carefully selected patients with spinal metastases.
