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
Introduction: Unilateral biportal endoscopic surgery (UBES) has emerged as a promising minimally invasive technique for treating lumbar spine disorders. However, a comprehensive evaluation of its long-term outcomes still needs to be improved. Aims and Objectives: This prospective study aimed to evaluate the efficacy and safety of posterior decompression for lumbar disc prolapse done by unilateral biportal endoscopy (UBE), including neurological improvement, functional status, and complications. Materials and Methods: Consecutive patients undergoing UBES were included from a tertiary care center, Hamidia Hospital, associated with Gandhi Medical College, Bhopal, Madhya Pradesh. Demographic data, pre-operative clinical characteristics, and surgical details were collected. Neurological improvement was assessed at preoperative, 2 weeks, 6 weeks, 3 months, 6 months, and 1 year postoperatively. Functional assessment using Visual Analog Scale (VAS) scores, Oswestry disability index (ODI), and Macnab criteria was performed at pre-operative, 2 weeks, 6 weeks, 3 months, 6 months, and 1 year postoperatively at each follow-up visit. Results: 50 patients of lumbar disc prolapse (66% male and 34% female) with a mean age of 40.38 ± 9.76 were enrolled, who underwent posterior decompression by UBE surgeries, most performed at L4-L5 (42%) and L5-S1 (40%) levels. Neurological status significantly improved postoperatively, with sustained enhancement in 1 year (96% improvement). Functional assessment revealed significant reductions in ODI scores (from 84.52 ± 4.04 preoperatively to 14.18 ± 3.2 [P = 0.001] at 1 year), VAS scores for back and leg pain (from 8.40 ± 0.756 preoperatively to 0.40 ± 0.495 [P = 0.001] at 1 year), and Macnab criteria outcomes as excellent at 1 year in 96% of patients. Conclusion: UBES demonstrates favorable outcomes for lumbar disc prolapse on 1-year follow-up, including neurological improvement, pain relief, and functional outcomes. UBES represents a promising minimally invasive approach for treating lumbar spine disorders, potentially enhancing patient quality of life.
