Pyridostigmine Treatment for Pediatric Axonal Guillain-Barré Syndrome.
Article in Muscle & nerve, 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
INTRODUCTION/
aimsDirect involvement of the neuromuscular junction (NMJ) in the inflammatory process of Guillain-Barré syndrome (GBS) has been described. Despite this, the NMJ very rarely serves as a target for direct medical intervention in GBS. Here, we report the use of an acetylcholinesterase inhibitor, pyridostigmine, in four pediatric patients with axonal GBS.
methodsAll patients received standard immune therapy. Pyridostigmine treatment was started 7 weeks to 5 months after disease onset, and 5-11 weeks from reaching the plateau phase. Treatment efficacy was monitored by the 6-min walk, quadriceps femoris and hamstring strength (manual muscle testing), the pediatric evaluation of disability inventory-functional skills, and the GBS disability score. All tests were performed before and during drug intervention.
resultsAll treated patients showed marked improvement in their motor and functional abilities. After 1 month of treatment, quadriceps femoris and hamstring strength increased by at least two points, and walking distance increased by 10-272 m. The pediatric evaluation of disability inventory functional skills mobility test increased by 22.3-34.7 points. No serious side effects were documented. DISCUSSION: Pyridostigmine may be a safe and effective add-on treatment in pediatric patients with axonal GBS who show insufficient response to immune therapy, and may be effectively used even at a late stage. Additional, larger studies are needed.
