In previous studies that showed increased MSNA in T2DM, untreated T2DM patients were included (Straznicky et al., 2012) or although treated T2DM patients were included, the high average values of insulin‐related indices (e.g., HOMA‐IR) in those studies might have affected the different MSNA results from our study (Huggett et al., 2005, 2003). Here, INS is linked to type 2 diabetes mellitus.
