a
Based on penalized imputation in which participants with missing values at follow-up are assumed to be smoking. Participants who were deceased at the time of follow-up are not included.
b
Models include adjustment for the following covariates (obtained during the baseline interview): total number of quit attempts lasting ≥24 h, alcohol intake, self-rated health, and depressive symptoms as measured by the Hospital Anxiety and Depression Scale (<8 vs. 8+).
c
Based on complete case analysis.
