Intrathecal Antibody Synthesis in Autoimmune Nodopathy.
Article in Journal of the peripheral nervous system : JPNS, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundAutoimmune nodopathy (AN) is caused by autoantibodies targeting the nodes of Ranvier or paranodes. AN frequently affects cranial nerves and spinal nerve roots and may accompany central demyelination, all of which belong to the intrathecal compartment. We aimed to ascertain the frequency of intrathecal antibody synthesis and blood-CSF barrier (BCSFB) dysfunction in AN and their clinical correlates.
methodsWe analyzed paired cerebrospinal fluid (CSF) and serum samples from 110 patients with AN, chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and Guillain-Barré syndrome (GBS). BCSFB dysfunction and intrathecal total IgG synthesis were assessed using Q
resultsCompared to CIDP and GBS, AN patients more frequently exhibited BCSFB dysfunction (87.5%) and intrathecal total IgG synthesis (68.8%). Among AN patients with cranial nerve or brain involvement (8/16, 50%), all had either an elevated IgG index (n = 7) or CSF-specific oligoclonal bands (n = 1). Intrathecal autoantibody synthesis was confirmed in 2 patients. Notably, both patients initially presented with cranial neuropathies. No CSF-restricted AN autoantibodies were found in the 39 seronegative CIDP and GBS patients.
conclusionsAN exhibits distinct immunopathogenesis compared to CIDP and GBS. Intrathecal synthesis of total IgG is associated with cranial nerve or central nervous system involvement, while that of AN-specific autoantibodies relates to cranial nerve onset diseases.
