a
Residential mobility was defined by comparing address at birth vs at diagnosis; Movers (55%): distance between addresses at birth and diagnosis > 100m; Non-movers (45%): distance ≤ 100m
b
Adjusted for all variables in the table
c
Based on all address information from birth to diagnosis provided by LexisNexis
