Abstract

PurposeThe aim of this study was to assess the relationship between specific erythrocyte fatty acids levels and vascular health in type 1 diabetes (T1D) with and without insulin resistance (IR).MethodsWe analysed baseline pretreatment data in a subset of 23 patients with T1D from a previously publis...
