More pronounced effects of the extent of discectomy over the extent of laminectomy on postoperative biomechanics and clinical outcomes in unilateral biportal endoscopy for lumbar disc herniation.
Article in Journal of orthopaedic surgery and research, 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
backgroundUnilateral biportal endoscopy (UBE) can be performed to treat lumbar disc herniation (LDH). Nevertheless, the postoperative clinical outcomes and spinal biomechanical implications following partial discectomy and laminectomy, which are inherent to UBE techniques for treating LDH, lack robust documentation in the literature.
methodsA total of 132 patients underwent UBE surgery for LDH at the L4-L5 segment. On the basis of intraoperative determinations, cases were classified as conservative discectomy (CD) or aggressive discectomy (AD) depending on the extent of discectomy. Postoperative three-dimensional computed tomography (CT) was used to categorize the extent of laminectomy into the following groups: one-third laminectomy (LC
resultsStatistically significant differences in both VAS scores for back pain and ODI scores were observed between the CD + (LC
conclusionsEarly postoperative dissatisfaction after UBE may be correlated with excessive disc resection and excessive laminectomy. During UBE procedures, the degree of disc resection has a greater effect on both clinical outcomes and segmental biomechanics than the extent of laminectomy.
