As expected, several baseline characteristics differed between the two groups (GD vs non-GD), among which are the following: age was higher in non-GD group [4]; prevalence of preexisting autoimmune diseases was higher in GD group [22]; higher ALT and GGT serum levels and higher number of patients with abnormal ALT and/or GGT were found in GD group [7]; NEU, GO and GDerm were present only in GD patients, with prevalences consistent with that reported in the current literature (i.e., 4.9%, 26.2% and 1.6%, respectively) [1, 5, 8]. Here, GPT is linked to autoimmune disease.
