~Included pharmacotherapy costs.
aThe expected quit attempts is the average number of quit attempts weighted by probability of successful or failed quit attempt event (TreeAge). ACER = average cost-effectiveness ratio; ICER = incremental cost-effectiveness ratio; MI = motivational interviewing; HE = health education; BA = brief advice.
b90% uncertainty interval (UI).
