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: Herniations of the intervertebral disc into the vertebral body, known as Schmorl's nodes (SNs), are frequently associated with degenerative disc disease (DDD). Painful SNs can contribute to discogenic lower back pain associated with DDD. Studies show that percutaneous endoscopic lumbar discectomy (PELD) yields favorable treatment outcomes for degenerative spinal diseases. This study retrospectively evaluated the efficacy of PELD in treating painful SNs. Objective: To evaluate the clinical efficacy and safety of PELD in treating patients with painful SNs. Methods: From February 1, 2020, to February 1, 2023, 13 patients with discogenic back pain from painful SNs (confirmed via intraoperative discography) who underwent single-level PELD at the index SN level were enrolled in the current study. Clinical data were retrospectively analyzed. Outcome measures, including the visual analog scale (VAS) for back pain and the Oswestry Disability Index (ODI), were recorded preoperatively and at 1 day, 6 months, and 12 months postoperatively. MRI scans of the lumbar region for all patients were evaluated preoperatively and again at the one-month follow-up. Results: All 13 patients were successfully treated with percutaneous endoscopic lumbar discectomy (PELD), showing significant postoperative improvements in VAS and ODI scores. Postoperative lumbar MRI revealed degenerative disc material in the SN cavities, which was removed using PELD. No surgical issues such as infections or nerve root damage, were noted. Conclusion: Postoperative MRI confirmed the removal of degenerative disc material, reinforcing PELD's efficacy in treating the pathological changes associated with painful SNs. No surgical complications, such as infections or nerve root damage, were seen, underscoring the safety of PELD. This study demonstrates that PELD effectively manages discogenic lower back pain caused by SNs.
