Is the study done in England (sheffield?)using a huge dataset of celiac patients included

The short version: the retrieved evidence does not include a Sheffield-based large-dataset study of celiac patients and neuropathy, so the specific study you are asking about is not in these records.

The evidence here contains several studies on celiac disease and neuropathy, but none from Sheffield and none using a large dataset. A 2010 study of 274 celiac patients (125 elderly, 149 young adults) found neuropathy in 11% of the elderly and 4% of the young adults [2], but that was a clinical comparison, not a population-level dataset. A 2005 study of 26 well-controlled celiac patients found 23% had peripheral neuropathy on testing [1], but again a small clinical sample.

The retrieval also includes a 2025 study using TCRβ repertoire sequencing from 884 celiac cases and 3,624 controls [3], and a 2025 whole-genome RNA sequencing study of 283 pediatric samples [4], but neither addresses neuropathy at all. A 2008 study on celiac disease and type 1 diabetes mentions peripheral nerve function in its title but the extracted data covers haptoglobin polymorphism, not nerve outcomes [5].

What is missing: any population-level study from Sheffield, any UK-based large dataset on celiac patients, and any study that systematically measures neuropathy rates across a large celiac cohort. The question of whether a specific Sheffield study found an association with neuropathy cannot be answered from these records.

My call: the evidence here does not contain the study you are asking about. The link between celiac disease and neuropathy is supported by smaller clinical studies [1][2], but no large-dataset Sheffield study is present in this retrieval.

Confidence: high that the specific study is absent from these records.
