Blood 1-Deoxysphingolipid Levels Are Associated With Epidermal Denervation in Small Fiber Neuropathy.
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 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
aimsDysfunctional sphingolipid metabolism leads to nerve fiber degeneration, particularly of small caliber Aδ and C fibers, in hereditary sensory and autonomic neuropathies. We aimed to investigate the association of blood 1-deoxysphingolipid (1-deoxySL) profiles and skin denervation in idiopathic small fiber neuropathy (SFN).
methodsSeventy-five patients with idiopathic SFN were recruited prospectively. Patients underwent a skin punch biopsy at the lower leg and upper thigh for intraepidermal nerve fiber density (IENFD) quantification. IENFD was correlated with individual blood 1-deoxySL levels, amino acid profiles, and determinants of glucose and lipoprotein metabolism.
resultsMedian distal IENFD in SFN patients was 5.3 fibers/mm. In 38/75 (51%) patients, IENFD was ≤ 5.3 fibers/mm (i.e., "low fiber density," LFD), while in 37/75 (49%) patients, IENFD was > 5.3 fibers/mm (i.e., "high fiber density," HFD). 1-deoxySL was higher in patients with LFD compared to HFD (p < 0.05). Fasting plasma glucose was also higher in patients with LFD than in patients with HFD (p < 0.01), while HDL was lower in patients with LFD compared to HFD (p < 0.001).
interpretation1-deoxySL, lipoprotein metabolism, and glucose levels are associated with the extent of epidermal denervation in SFN, supporting the role of this metabolic axis in small nerve fiber pathology.
