Adjusted odds ratio (AOR) predicting likelihood of change in wave 1 smoking status. AORs controlled for sex, age, race, education, income, age of smoking initiation, and wave 1 ECIG use status. For current smokers, AORs greater than 1 represent increased likelihood of being a former smoker at wave 2. For former smokers, AORs greater than 1 represent increased likelihood of being a current smoker at wave 2. Bold text indicates significant AOR (p < 0.05). No analyses survived Bonferroni adjustment for multiple comparisons (p < .004). CI = confidence interval; OR = odds ratio.
