*
Recipients of live donor kidneys, recipients of kidneys from deceased donors seropositive for hepatitis C or hepatitis B, and recipients of kidneys from deceased donors that met criteria as ECD-DCD, ECD-DIRVI, DCD-DIRVI, or ECD-DCD-DIRVI were excluded. P-values represent comparisons across all groups. Percentages were calculated among individuals without missing data for that variable.
