Acute Urinary Retention and Guillain-Barré Syndrome: A Zebra or a Horse.
Article in Journal of the American College of Emergency Physicians open, 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
Acute immune-mediated polyneuropathies are grouped under the umbrella term Guillain-Barré syndrome (GBS). GBS can often present with variable clinical findings. Typical features of GBS include a progressive, symmetric muscle weakness and absent deep tendon reflexes. This case report describes a confusing presentation in a patient who had been having preceding back pain prior to the onset of a worsening back pain associated with autonomic symptoms of GBS with urinary retention. This caused initial diagnostic confusion with cauda equina syndrome being the leading diagnostic possibility until ruled out with magnetic resonance imaging. The case demonstrates the importance of not anchoring completely on the initial diagnostic probability but on continuing the workup of acute urinary retention associated with other neurologic symptoms as cauda equina was effectively ruled out. The case also highlights the sometimes problematic errors that can occur with observation medicine.
