Impact of degenerative disc changes on the early outcomes in patients undergoing full-endoscopic lumbar discectomy-a prospective study.
Article in Porto biomedical journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Introduction: Lumbar disc herniation (LDH) is a prevalent condition that can cause radiculopathy and leg pain. Full-endoscopic lumbar discectomy (FELD) has emerged as a minimally invasive alternative to microdiscectomy, offering similar clinical efficacy with potentially reduced recovery times. Degenerative disc disease (DDD) is frequently observed in patients undergoing surgery, yet its influence on surgical early outcomes of FELD remains unclear. Methods: This prospective study included 91 patients who underwent FELD for single-level LDH between January 2022 and March 2024. Patients were classified in two groups based on Pfirrmann grade: grade inferior to 4 (Group 1) and grade 4 or 5 (Group 2). Clinical outcomes were assessed using the Numeric Rating Scale (NRS) for back and leg pain preoperatively and at 2, 14, 30, and 90 days postoperatively, and the Oswestry Disability Index (ODI) preoperatively and at 30 and 90 days postoperatively. Results: Among the 91 patients, 89% had advanced disc degeneration (Pfirrmann grade 4 or 5). Preoperatively, Group 1 (all Pfirrmann 3) had significantly higher back pain (NRS 8.2 vs. 5.2, Discussion: Patients with moderate disc degeneration (Pfirrmann grade 3) exhibited greater preoperative back pain but experienced superior back pain relief after FELD compared with those with advanced degeneration (Pfirrmann grade 4 or 5).
