CI = confidence interval; NH = Non-Hispanic.
aWeighted percentages report the percentage of respondents from each quit attempt category who had the specific cessation outcome (eg of respondents who reported trying to quit unassisted, 68.9% had not quit at either wave).
bEstimates from multinomial logistic regression with four-category outcome variable. Reference group: no quit at both Waves 2 and 3.
cEstimates unstable due to limited sample size.
