a
Study population defined as those <18 years of age at baseline and ≥18 years of age at 2003FU (n = 2,022).
b
Number (%) = participants in the row who are ever- or current smokers.
c
Missing information: race (n = 10) and youth attention problems (n = 40).
d
Some survivors are represented in more than one treatment category. Treatment information is missing for survivors without medical chart abstractions (n = 124).
