Comparing Unilateral Biportal Endoscopic Discectomy Versus Microdiscectomy for Lumbar Disc Herniation: A Systematic Review and Meta-Analysis.
Review in Global spine journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Study DesignThis study is a meta-analysis of randomized controlled trials (RCTs) and observational studies.ObjectiveLumbar disc herniation (LDH) often requires surgery, with microdiscectomy (MD) being common. This study compares Unilateral Biportal Endoscopic Discectomy (UBED) to conventional and tubular MD for LDH treatment.MethodsPubMed, Cochrane Central, and ScienceDirect were searched up to May 2025. Mean differences (MDs) and risk ratios (RRs) were pooled with a random effects model using Review Manager. Quality was assessed using the Cochrane risk of bias tool and the Newcastle-Ottawa Scale. Publication bias was evaluated with funnel plots and Egger's regression test.ResultsThirteen studies (11 observational studies and 2 RCTs), pooling 1369 patients, were included. UBED was associated with decreased 1-3 days post-operative (MD: -0.81; 95% CI: [-1.48, -0.14];
