Cognitive impairment in chronic inflammatory demyelinating polyneuropathy.
Article in Journal of neurology, 2025. 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
introductionCognitive dysfunction has been repeatedly described as an aspect of chronic inflammatory demyelinating polyneuropathy (CIDP), but to which capacities this exactly refers and how it is embedded in the clinical phenotype of the condition remains unknown. Therefore, the detailed cognitive profiles of persons with and without CIDP were compared with each other and the disease-related results analyzed in view of main symptom complexes.
methods44 persons with CIDP were studied with respect to their cognitive performances in an extensive computer-based test battery and described clinically in terms of sensorimotor disability (R-ODS), fatigue (FSMC), and mood (DESC-I). The cognitive test results were compared to those of 33 age-matched healthy controls.
resultsThe overall cognitive performance of persons with CIDP was significantly worse than that of controls (composite score for CIDP: 33.34 ± 17.96; for Controls: 48.73 ± 18.31; U = 382, p < 0.001). Pronounced deficits prevailed in processing speed (q = 0.018), executive function (q = 0.018), memory (short-term: q = 0.020; long-term: q = 0.025) and visuoconstruction (q = 0.018). Using a hierarchical regression model, the inclusion of the factor sensorimotor disability improved the prediction of overall cognitive performance in persons with CIDP (p = 0.027).
conclusionCognitive impairment is an under-recognized aspect of CIDP, characterized by reduced processing speed, executive functioning, and memory performance. These cognitive deficits grow together with sensorimotor impairment. The findings show that CIDP goes along with functional changes beyond its classical lead symptoms.
