The table reports the median age of the enrolled subjects and the numerical results of the study, before (T0) and after the 2-month intervention (T2). Parametrical data (HDL, LDL and total cholesterol, pCS, FMD, glycaemia, HbA1c) are represented as mean ± SD, non-parametrical ones (age, IS) are reported as median and interquartile range; p-values of t-student and Wilcoxon tests of the differences between T0 and T2 are reported, respectively. Age, LDL and total cholesterol data already published by De Angelis et al. [25]. Abbreviations: HDL (high-density lipoprotein), LDL (low-density lipoprotein), pCS (p-cresyl sulfate), IS (indoxyl sulfate), FMD (flow-mediated dilation), HbA1c (glycated haemoglobin).
