Clinical and Functional Outcomes of Posterior Endoscopic Decompression for Symptomatic Cervical Disc Herniation.
Article in Cureus, 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
introductionPosterior endoscopic decompression is a minimally invasive alternative for symptomatic cervical disc herniation management. We aimed to evaluate the clinical and functional outcomes of posterior endoscopic decompression in patients with symptomatic cervical disc herniation. The objectives were to assess postoperative improvement in pain and disability, determine patient-reported functional outcomes using the Modified MacNab criteria, and analyze the influence of demographic and clinical variables on surgical success. MATERIALS AND
methodsThis single-center study included 145 patients with symptomatic cervical disc herniation treated with posterior endoscopic decompression. Preoperative and postoperative assessments included Visual Analog Scale (VAS) scores for arm and neck pain and Neck Disability Index (NDI) scores. Patients were followed up at 1, 6, and 12 months postoperatively. Functional outcomes were evaluated using the Modified MacNab criteria. Statistical analysis was performed using repeated-measures analysis of variance and Pearson's chi-squared test, with significance set at p < 0.05.
resultsThe study included 82 (56.6%) males and 63 (43.4%) females with a mean age of 48.3 ± 9.7 years. The most commonly affected levels were C5-C6 in 61 (42.1%) patients and C6-C7 in 59 (40.7%). Mean arm pain VAS score significantly improved from 7.6 ± 1.2 preoperatively to 1.9 ± 1.0 at 12 months (p < 0.001). Mean neck pain VAS score decreased from 5.1 ± 1.8 to 2.2 ± 1.1 (p < 0.001), while mean NDI score improved from 54.3 ± 10.5 to 19.8 ± 8.2 (p < 0.001). According to the Modified MacNab criteria, excellent outcomes were observed in 72 patients (49.7%), and good outcomes were observed in 48 patients (33.1%), resulting in an overall success rate of 82.8%. Paracentral disc herniation demonstrated significantly better outcomes than foraminal herniation (p = 0.042).
conclusionPosterior endoscopic decompression provides significant pain relief, functional improvement, and favorable clinical outcomes in patients with symptomatic cervical disc herniation, representing an effective and minimally invasive surgical treatment option.
