a
In some analyses the sample size was smaller than the total due to missing cases.
b

OR: odds ratio. CI: confidence interval.
c
Adjusted Model 1: Adjusted for gender, age, education and country.
d
Adjusted Model 2: Adjusted for sociodemographic characteristics as well as self-efficacy and nicotine dependence.
e
Reference value was for those without the health concern/condition, and this applies to all conditions.
