Small fiber neuropathy in irritable bowel syndrome.

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
Aim: In this study, we intend to evaluate the occurrence of small fiber neuropathy in patients with irritable bowel syndrome (IBS). Background: Small fiber neuropathy (SFN) is a sensory neuropathy that results from the degeneration of small Aδ and unmyelinated C fibers. SFN manifests positive symptoms, such as tingling, burning, prickling, and aching, and negative symptoms, including numbness, tightness, and coldness. The SFN coexistence with other comorbidities (e.g., fibromyalgia, inflammatory bowel disease, celiac disease) has been reported in previous studies. Methods: We conducted a cross-sectional study to assess the coexistence of SFN and IBS. Forty-two IBS patients and forty-three healthy individuals were asked to complete the Michigan Neuropathy Screening Instrument (MNSI) questionnaire. Results greater than three (>3) were considered positive. Participants with positive MNSI questionnaire results were examined for any neuropathy signs according to the Utah Early Neuropathy Scale (UENS) examination. The participants with positive results for the questionnaire and examination were checked for the sural and the superficial peroneal nerve conduction study (NCS). Normal NCS represented intact large fibers and the diagnosis of SFN. Results: Ten participants, 7 (16.7 %) in the IBS group and 3 (6.9 %) in the healthy group, had positive results for the questionnaire. Four participants were positive for the examination, with normal NCS, and were classified as SFN-positive. All four SFN diagnoses were from the IBS group. No one in the healthy group was diagnosed with SFN. We could find a significant statistical difference (p<0.05) between the IBS and healthy groups regarding the prevalence of SFN diagnosis. Conclusion: The co-occurrence of SFN and IBS suggests the possibility of a generalized neuropathy syndrome characterized by widespread neuronal impairment. Thus, any peripheral neuropathy symptom in IBS patients (and potentially other chronic pain disorders) should be evaluated for SFN since timely diagnosis and proper treatment result in a better quality of life for the patients.
