Data are descriptive (weighted and unadjusted). aOR: adjusted odds ratio. CI: confidence interval. Overall, 71.3% (n = 1625) of respondents selected that quitting smoking was a reason for vaping.
Models are weighted and adjusted. Device type is the independent variable in all models. Model 1 adjusted for age, sex, country, smoking frequency and vaping frequency. Models 2–4 adjusted for age, sex, smoking frequency and vaping frequency.
Significant difference between pre-filled cartridges/pods and open-tank systems: Model 1: tanks vs. cartridges/pods: aOR: 1.62 (1.21–2.17). Model 2 (Canada): tanks vs. cartridges/pods: aOR: 1.72 (1.13–2.61).
Statistical significance and confidence intervals were computed at the 95% confidence level for all analyses.
