^aNote. The Hosmer-Lemeshow goodness-of-fit test: χ² = 18.32, p = .306; reference is very addictive.

^bThe Hosmer-Lemeshow goodness-of-fit test: χ² = 10.26, p = .853; reference is very addictive.

^cOdds ratios adjusted for sex, race/ethnicity, age, total number of other tobacco products (cigars, hookah, and smokeless tobacco), mother’s education, father’s education, and school type.

^dBolded p values indicate significance when α < .05.
