Cauda Equina Syndrome Associated with Dural Ectasia in Ankylosing Spondylitis: Case Report.
Article in Asian journal of neurosurgery, 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
Cauda equina syndrome (CES) associated with dural ectasia is a rare manifestation in patients with ankylosing spondylitis (AS). We report a case of a 53-year-old female with a 10-year history of AS who developed CES in the past 1 year. The CT and MRI findings revealed the unique appearances of dural ectasia, multiple ventral dural diverticula, erosion of lumbar vertebral bodies, adhesion of the nerve roots of the cauda equine, and the conus medullaris to the wall of the dural sac. Due to progressive clinical deterioration, surgical decompression was performed via laminoplasty with filum terminale resection to release adhesions involving the conus medullaris and nerve root. Postoperatively, constipation, urinary incontinence, and muscle strength improved. The possible mechanisms of CES associated with chronic AS are discussed.
