Clinical Efficacy of Percutaneous Endoscopic Discectomy for the Treatment of Lumbar Disc Herniation in Patients Over 70 Years Old.
Article in Clinical spine surgery, 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
STUDY
designA retrospective study.
objectiveTo study the efficacy of percutaneous endoscopic discectomy (PED) for treating LDH patients over 70 years old. SUMMARY OF BACKGROUND DATA: PED is considered an effective surgical method for treating LDH, but few studies have focused on the clinical efficacy of PED in elderly patients with LDH. MATERIALS AND
methodsLDH patients over 70 years old with radicular pain or signs of radiculopathy were included. All patients underwent PED under local/general anesthesia. Operative time, length of hospital stay, complications, visual analogue score (VAS) and the Oswestry Disability Index (ODI) were assessed preoperatively, 3 days postoperatively, 3 months postoperatively, 6 months postoperatively, and 12 months postoperatively. A paired-sample t test was performed to compare differences in the ODI and VAS scores between the preoperative, postoperative and follow-up periods.
resultsA total of 132 patients over 70 years old with LDH were included. The average age was 75.31 years. No related complications occurred, and there was no recurrence of LDH within 12 months after surgery. The differences in the VAS scores and the ODI scores before and after surgery were statistically significant ( P <0.0001). Differences in the ODI scores at 3 months, 6 months, and 12 months after surgery were statistically significant ( P <0.0001). There were significant differences in the VAS scores at 3 days, 3 months, and 6 months after surgery ( P <0.0001). However, the differences in VAS scores between 6 months after surgery and 12 months after surgery were not statistically significant ( P =0.083).
conclusionsOur results demonstrated that PED is a safe and effective technique for elderly patients with LDH and that it yields significant improvements in pain and functional outcomes.
