Fatal Spinal Cord Edema Following Cervical Decompression Surgery Possibly Associated with Dialysis Disequilibrium Syndrome: A Case Report.
Article in JMA journal, 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
Dialysis disequilibrium syndrome (DDS) is a rare neurological complication of hemodialysis caused by rapid osmotic shifts. While its cerebral effects are well recognized, its impact on the spinal cord has not been well documented. We report the fatal case of a 57-year-old man on maintenance hemodialysis who developed progressive spinal cord edema 15 days after posterior cervical decompression surgery. The patient's neurological deterioration occurred in temporal association with each hemodialysis session, during which the patient exhibited significant fluctuations in blood urea nitrogen (pre-dialysis range: 54.8-122.9 mg/dL). Despite aggressive management, including extended dialysis and continuous renal replacement therapy, his condition worsened. Autopsy revealed extensive spinal cord necrosis at the surgical site, with findings consistent with severe, recurrent edema and its compressive effects, without evidence of a primary ischemic or inflammatory pathology. This case suggests a devastating, atypical manifestation of a DDS-like pathophysiology, where the surgically compromised spinal cord may have become a vulnerable target for osmotic shifts, underscoring the need for a high index of suspicion in post-neurosurgical patients undergoing hemodialysis.
