Note. Data are presented as number (%) except for age and dialysis duration, which are presented as median (interquartile range).
a
Income was categorized according to fifths of average neighborhood income (first quintile is the lowest and the fifth quintile is the highest).
b
Urban location indicates a population >10 000 or a population >1000 with population density >400/km2.
c
Recipients identified as pre-emptive were assessed for the presence of dialysis codes and re-classified as hemodialysis (n = 22) or peritoneal dialysis (n = 14).
