Abbreviation: HR, hazard ratio.
a
Adjusted multivariable Cox proportional hazards regression analysis model includes the following covariates: age at study entry, material and social deprivation indices as continuous variables, ethnicity (CAN-Marg ethnic concentration index as continuous variable), sex, rurality, and diagnosis era.
b
Twenty additional individuals with missing or unavailable CAN-Marg ethno-cultural composition index; thus, the remaining cohort included 1055 children who used a pump users and 1844 who did not use a pump.
c
Twenty-six additional individuals with missing or unavailable CAN-Marg ethno-cultural composition index; thus, the remaining cohort included 102 children who used a pump users and 508 who did not use a pump.
