Income quintile is a measure of neighborhood socioeconomic status that divides the population into five income groups of equal size. Group 1 lives in the neighborhoods with the lowest incomes and group 5 in those with the highest incomes.
Ethnocultural composition refers to the community makeup of immigrants (i.e. proportions of recent immigrants, of people born outside Canada, of those who self-identify as visible minorities and of those who cannot speak either of Canada's official languages—English and French). The population is divided into five ethnocultural quintiles of equal size. Group 1 lives in the neighborhoods with the greatest degree of ethnocultural composition, and group 5 lives in those with the least [18].
Baseline eGFR within 7 days to 3 years prior to dialysis start.
P-values were calculated using the Chi-Squared test for analysis of categorical variables. eGFR, estimated glomerular filtration rate.
