Small fiber neuropathy associated with COVID-19 infection and vaccination: A prospective case-control study.
Article in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundSmall fiber neuropathy (SFN) after both COVID-19 infection or vaccination has been reported in sporadic cases, but a detailed description and comparison are missing. We aimed to screen a large cohort of patients complaining of pain and autonomic symptoms after COVID-19 natural infection or vaccination to ascertain the presence of SFN and its correlation with autoimmune diseases.
methodsWe prospectively recruited for this case-control study 66 patients: 33 developing sensory and autonomic symptoms after a natural COVID-19 infection (P-COVID) and 33 after a mRNA vaccination against COVID-19 (P-VAC). We also used 33 matched healthy controls (HC) collected before 2019 when the COVID-19 virus appeared. Patients underwent neurological examination and clinical scales, an extensive serum screening, and skin biopsy to detect small nerve fiber involvement.
resultsClinical scales showed higher scores for autonomic symptoms in P-COVID patients than in P-VAC patients, but the other scales did not differ. P-COVID and P-VAC patients showed a significant decrease in somatic small nerve fibers compared with HC, whereas autonomic innervation did not differ. SFN was more frequent in P-COVID patients (94%) than in P-VAC patients (79%). Epidermal innervation was correlated with clinical scales for pain and autonomic dysfunctions. Autoimmune abnormalities were frequent in both groups but importantly they were not correlated with SFN.
conclusionsSomatic SFN was frequently found in both P-COVID and P-VAC patients, with a higher incidence in the former group. Spared skin autonomic innervation was spared in both groups although a subtle autonomic involvement in P-COVID patients was suggested by a high COMPASS-31 scale score. SFN was not correlated with autoimmune dysfunctions, although autoimmune diseases were frequent in both groups.
