Prognostic factors of patients with spinal malignant melanoma after surgical intervention: a case series of 21 patients and literature review.
Article in Journal of neuro-oncology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundSpinal malignant melanoma (SMM) is a rare type of tumor that can cause nerve roots or spinal cord compression. Patients often suffer from fierce pain and paralyzation. And the estimated survival time were less than 6 months. Surgical interventions to remove the tumor and decompress the nearby nerve roots and spinal cord are effective management. Unfortunately, there lack a thorough and persuasive surgical guideline that specifically aims for this disease. It is necessary to obtain some clinical prognostic factors that predict the recurrence rate and overall survival (OS) of patients with SMM who underwent surgical interventions.
methods21 patients with SMM who underwent surgical intervention were retrospectively reviewed. Related patients factors, treatment factors and tumor factors were acquired and subjected into survive analyses using Kaplan-Meier method and the log-rank test. Further Cox proportional hazards model was used to identify independent prognostic factors. Literature regarding surgical interventions on SMM patients were reviewed and summarized as well.
resultsSurgical approach total en-bloc spondylectomy (TES/Piecemeal) (p = 0.015, B 0.029, 95%CI 0.002-0.508), preoperative Frankel grade (A-C/D-E) (p = 0.021, B 15.041, 95%CI 1.492-151.669) and tumor metastases (Yes/No) (p = 0.013, B 16.667, 95%CI 1.805-153.897) are independent prognostic factors for recurrence free survival (RFS). Preoperative Frankel grade (A-C/D-E) (p = 0.031, B 10.676, 95%CI 1.241-91.877) is independent prognostic factors for OS. 12 literatures have been reviewed, including 11 case reports and one retrospective study.
conclusionsSurgical interventions for patients with SMM are beneficial. Surgical approach (TES/piecemeal), tumor origin (primary/metastasis) and preoperative Frankel grade (A-C/D-E) are independent risk factors in predicting RFS. Preoperative Frankel grade (A-C/D-E) is independent prognostic factor in predicting OS.
