Continuous variables are expressed as mean (SD, standard deviation). Categorical variables are expressed as the number of patients (%). BMI: body mass index; NYHA FC: New York Heart Association functional class. Post hoc comparisons between groups were not statistically significant otherwise indicated ⦿: significant difference between G2 and G1; : significant difference between G3 and G1; ❖: significant difference between G3 and G2.
