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: Degenerative changes, such as osteoarthritis, often lead to facet joint syndrome (FJS). Standard treatments include physical therapy, nerve blocks, and radiofrequency rhizotomy. Full-endoscopic lumbar rhizotomy enables direct visualization and precise ablation of the medial branch nerves. Recent studies have shown significant reductions in pain and disability. This study aimed to evaluate the efficacy and safety of full-endoscopic rhizotomy in patients with degenerative lumbar FJS, using pooled data from clinical studies reporting postoperative outcomes. Methods: A systematic literature search was conducted in PubMed and Scopus databases between January 2000 and March 2025, following PRISMA guidelines. Studies reporting preoperative and postoperative outcomes of full-endoscopic rhizotomy in adult patients (18 years of age or older) with lumbar FJS were included. Both randomized controlled trials (RCTs) and observational studies were considered. Risk of bias was assessed using the Cochrane RoB 2 tool for RCTs and Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I) for non-randomized studies. Primary outcomes included changes in pain and disability scores measured by the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI). Meta-analyses were performed using pooled mean differences with 95% confidence intervals (CIs). Results: Fourteen studies involving a total of 1,467 patients were included. The pooled mean improvement in VAS was -4.36 (95% CI: -4.42 to -4.31), and the mean improvement in ODI was -32.32 (95% CI: -32.84 to -31.80), indicating significant pain and functional improvement after endoscopic rhizotomy. No study reported any severe or permanent complications. Minor complications included transient skin numbness, intraoperative discomfort, and failed sutures. Endoscopic techniques demonstrated lower complication rates (6.67% Conclusions: Full-endoscopic rhizotomy is a safe and effective treatment for degenerative lumbar FJS, offering significant and sustained improvements in pain and disability. While it requires a longer operative time than conventional techniques, its satisfactory clinical outcomes and low complication rates support its use as a minimally invasive alternative. Further high-quality comparative studies are recommended to validate long-term benefits.
