Mid-to-Long Term Radiological and Clinical Outcomes of Oblique Lateral Interbody Fusion versus Posterior Lumbar Interbody Fusion for Severe Lumbar Spinal Stenosis: A Retrospective Comparative Study.
Article in Journal of pain 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
Purpose: To explore and compare the clinical efficacy and radiological changes of oblique lateral interbody fusion (OLIF) and posterior lumbar interbody fusion (PLIF) in patients with severe lumbar spinal stenosis (LSS). Patients and Methods: We retrospectively collected data from 34 patients with severe LSS (Schizas grade C or D) who underwent either OLIF or PLIF at our institution between June 2014 and June 2020. Imaging evaluation included the cross-sectional area (CSA) of the spinal canal and ligamentum flavum on MRI. Clinical evaluation included Visual Analogue Scale (VAS) scores and Oswestry Disability Index (ODI). Statistical analysis was performed using independent sample Results: The cross-sectional area of the spinal canal in the OLIF group was gradually expanded from 47.6 ± 16.5 mm Conclusion: OLIF technology provides significant mid-term (1-year) spinal canal dilatation and clinical improvement in severe LSS, achieving outcomes comparable to PLIF. Therefore, OLIF can be considered a viable and effective surgical option for severe LSS.
