In the comparison of the median values of variables between the pre-MMF-MT period (combined MMF-CNI or CNI alone) and the last outpatient review on MMF-MT (median of 78 months), only the median GFR value was significantly greater in the last review on MMF-MT [56 (15–126) mL/min/1.73 m2 vs. 61 (7–134) mL/min/1.73 m2; p = 0.001], whereas the frequency of diabetes and hypertension and laboratory values of hematological variables, serum creatinine and liver function (AST and ALT) did not show significant differences between the two periods (Figures 1, 2). The gene discussed is GPT; the disease is diabetes mellitus.
