consent rate	From screening to the end of treatment after 6 months	the number of eligible smokers who agree to participate divided by the number of eligible smokers
randomization rate	From screening to the end of treatment after 6 months	the number of participants who are randomized divided by the number of eligible smokers who consent to participate
attendance rate	From screening to the end of treatment after 6 months	the number of participants who complete the intervention divided by the number of participants who are randomized into the treatment arms (ST and II)
