Re-evaluation of different electrophysiological criteria for Guillain-Barré syndrome in a single cohort from China.

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
Background and aims: We aimed to compare electrophysiological subtypes of Guillain-Barré syndrome (GBS) in a single cohort from northern China using three criteria (Ho's, Hadden's, Rajabally's), to clarify whether GBS subtypes are affected by electrophysiological criteria and nerve conduction studies (NCS) examination timing, to explore the value of sural sparing in subtype classification, and analyze the association between conduction block (CB) and short-term prognosis of Acute Motor Axonal Neuropathy (AMAN). Methods: We retrospectively collected GBS patients hospitalized in the Department of Neurology, the Second Hospital of Hebei Medical University (Jan 2017-Jan 2022), who met Brighton diagnostic criteria and had complete NCS data. Patients were classified via three electrophysiological criteria (Ho's, Hadden's, Rajabally's); we analyzed subtype distribution by NCS timing (1, 2, or ≥3 weeks post-onset) and used discharge Hughes Functional Grading Scale (HFGS) to assess short-term prognosis. Results: A total of 262 patients were enrolled. AMAN was the main subtype (40.1% by Hadden's, 46.6% by Ho's, 59.5% by Rajabally's criteria). Fleiss Kappa showed strong consistency among the three electrophysiological criteria ( Conclusion: GBS electrodiagnosis depends on criteria and NCS timing (≥3 weeks more consistent). AMAN is predominant in our cohort from northern China regardless of criteria used. Sural sparing and serial NCS enhance subtype classification accuracy.
