Autonomic Nervous System Phenotyping Across Chronic Demyelinating Peripheral Neuropathies: A Comparative Study.
Article in Journal of the peripheral nervous system : JPNS, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimsThis study aimed to systematically phenotype autonomic nervous system (ANS) involvement in patients with chronic inflammatory demyelinating polyneuropathy (CIDP), monoclonal gammopathy of undetermined significance-associated neuropathy (MGUS-PNP), Charcot-Marie-Tooth disease Type 1A (CMT1A), and hereditary neuropathy with liability to pressure palsies (HNPP).
methodsAutonomic symptoms were assessed using the SCales for Outcomes in Parkinson's Disease-Autonomic Dysfunction (SCOPA-AUT). Muscle strength and functional disability were evaluated using the Medical Research Council (MRC) scale, the Inflammatory Neuropathy Cause and Treatment (INCAT) disability scale, and the Overall Neuropathy Limitation Scale (ONLS).
resultsA total of 343 participants were included: 98 with CIDP (mean age: 59.2 ± 13.2 years), 51 with MGUS-PNP (66.0 ± 11.3 years), 51 with CMT1A (51.2 ± 13.1 years), 18 with HNPP (40.6 ± 15.1 years), and 125 healthy controls (58.2 ± 13.3 years). Compared with healthy controls, patients with CIDP, MGUS-PNP, and CMT1A showed significantly higher total SCOPA-AUT scores (p < 0.01). Distinct, disease-specific ANS symptom patterns were observed across neuropathy subtypes. Overall disability was independently associated with overall autonomic symptom burden in MGUS-PNP (β = 0.42, p < 0.05) and CMT1A (β = 0.68, p < 0.05). In CIDP, patients with active disease showed higher autonomic symptom burden than those with inactive disease (12.7 ± 11.7 vs. 8.6 ± 7.9, p = 0.042).
interpretationPatients with CIDP, MGUS-PNP, and CMT1A exhibit a substantial autonomic symptom burden with distinct disease-specific ANS patterns. These findings highlight the relevance of autonomic dysfunction in immune-mediated and hereditary neuropathies and warrant further studies to clarify their clinical and prognostic significance.
