Learning curve analysis of unilateral biportal endoscopic technique in the treatment of the lumbar disc herniation combined with spinal stenosis.
Article in BMC surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo explore the learning curve and clinical efficacy of the unilateral biportal endoscopy (UBE) technique applied in the lumbar disc herniation combined with spinal stenosis.
methodsA retrospective study was conducted on 112 consecutive cases of lumbar disc herniation combined with spinal stenosis who received UBE at the Beijing Luhe Hospital, Capital Medical University from December 2022 to January 2024. The cohort was divided into the early group and the late group by using the cumulative summation (CUSUM). The baseline data, surgery-related data, visual analogue scale (VAS) scores, Oswestry disability index (ODI) scores and complications of the two groups were statistically compared.
resultsTaking the cutoff point of the learning curve as the grouping basis, patients were divided into the early group (25 cases) and the late group (87 cases), with the coefficient of determination R2 = 0.98. The comparison of baseline data, ODI scores and complications between the two groups of patients was not statistically significant (P > 0.05). The average operation time and single incision length in the late group were shorter than those in the early group, with a statistically significant (P < 0.05). In addition, compared with the early group, the average postoperative one-month VAS score of the late group significantly decreased (P < 0.05).
conclusionsUBE for the treatment of lumbar disc herniation combined with spinal stenosis can relieve pain, alleviate short-term symptoms, and reduce the operative time with clinical experience accumulated. The learning curve analysis in this study revealed that the operative competence in treating these complicated cases was obtained after primary attempt of twenty-five cases.
