General, biochemical, clinical and transplant-related characteristics of the donor population stratified by type of donors (SCD vs. ECD and unsuitable donors) in Group A (years from 1999 to 2005) and Group B (years from 2006 to 2013). Continuous variable are presented as mean ± standard deviation (SD), categorical as number and percentages (%).
