ACE and hyperlipidemia: Diabetic patients’ UM was less diverse than that of non-diabetics (p = 0.021, p = 0.028, p = 0.029, p = 0.033 and p = 0.017 for OTUs, ACE, iChao2, Shannon and Simpson indices, respectively) and subjects with elevated cholesterol and/or hyperlipidemia had less diverse microbiota than those with normal plasmatic lipid levels (p = 0.012 and p = 0.013 for ACE and iChao2, respectively).
