Functional outcomes after surgery for intradural extramedullary spinal tumors: A retrospective study.
Article in Surgical neurology international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Intradural extramedullary (IDEM) spinal tumors are predominantly benign lesions, and microsurgical excision remains the treatment of choice. Despite favorable outcomes reported in the literature, predictors of functional recovery remain clinically relevant, particularly in resource-limited settings. Methods: We retrospectively reviewed 170 consecutive patients who underwent microsurgical excision of spinal IDEM tumors at a single tertiary care center over a 10-year period. Preoperative neurological status was assessed using Frankel grading, and pain was evaluated using the Denis pain scale (DPS). All tumors were approached through a posterior, facet-sparing technique. Functional outcomes were assessed postoperatively, at 2 weeks, and at 6 months. Factors influencing outcomes were analyzed using univariate statistical methods. Results: Gross total resection was achieved in 93% of patients. At final follow-up, 157 patients (92.4%) demonstrated a good functional outcome, including 84 (49.4%) patients with ≥2-grade improvement in Frankel score. Poor preoperative neurological status (Frankel A-C) and ventral axial tumor location were significantly associated with poorer outcomes ( Conclusion: Microsurgical excision of IDEM tumors through a posterior, facet-sparing approach provides favorable neurological and pain outcomes with low morbidity. Preoperative neurological status and ventral tumor location are important predictors of postoperative recovery. Early surgical intervention remains critical for optimizing functional outcomes.
