Comparative efficacy of unilateral biportal endoscopy versus endoscopic foraminoplasty decompression for single-level lumbar spinal stenosis: a retrospective cohort study.
Article in Frontiers in 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
Objective: To compare perioperative, functional, and radiological outcomes of unilateral biportal endoscopic (UBE) decompression versus endoscopic foraminoplasty decompression (EFD) in patients with single-level lumbar spinal stenosis (LSS) using a retrospective observational design. Methods: A total of 208 patients with single-level LSS were screened; 161 were enrolled (UBE: Results: Baseline characteristics were comparable between groups (all Conclusion: This retrospective comparative observational study suggests that both UBE and EFD are safe and effective minimally invasive options for single-level LSS, with acceptable complication profiles. UBE is associated with shorter operation time and hospital stay but greater blood loss, whereas EFD offers reduced bleeding. Although UBE provides more extensive radiological decompression, functional outcomes at 12 months are comparable between the two techniques. The choice of procedure should be individualized based on stenosis morphology, patient comorbidities, and surgeon expertise. Given the non-randomized design, these findings should be interpreted as hypothesis-generating and require confirmation in prospective randomized trials.
