The utility of sural-sparing pattern in the electrodiagnosis of regional subtypes of Guillain-Barré Syndrome.
Article in Clinical neurophysiology practice, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveWe present an exemplar patient, illustrating utility of the sural-sparing pattern in diagnosis of Guillain-Barré Syndrome (GBS). We then present data that sheds light on the pathophysiology of sural-sparing. METHOD AND
resultsWe describe a case of complex ophthalmoplegia that exemplifies the challenge of diagnosing regional subtypes of Guillain-Barré Syndrome, and the value of scrutinizing sensory nerve action potentials for the sural-sparing pattern. We also demonstrate, in a series of GBS patients, how serial nerve conduction studies can reveal "covert" sural-sparing in patients without sural-sparing on the initial study. Finally, by studying the median and radial sensory nerve action potentials at digit I in GBS patients, we demonstrate that the likely pathology of sural-sparing is related to the predilection of median nerve for subclinical entrapment; where the blood-nerve barrier is deficient and therefore more exposed to the immunopathology of GBS.
conclusionIncorporating sural-sparing would improve the specificity of GBS electrodiagnosis; especially in difficult to diagnose regional subtypes of GBS.
