  1. 1Number varies due to item non-response
  2. 2Adjusted for all variables in the model, including gender, age, education, debut age for smoking and CPD
  3. 3The number of smokers who used medication, health service and web/mobile exclusively were low and included in the group of combined use. 2-tailed p value, where *** = p values< 0.001, ** p values< 0.01, *p values< 0.05
