* Outcomes predicted by the QBM for 1,000 quitters chosen at random from the population of smokers aged between 15 and 74 years at the time of quitting and followed for 10 years. Life-years, QALYs and costs discounted at 5% per annum; cases avoided and deaths not discounted.

^&Cases and deaths have been rounded to the nearest integer and hence the total presented may not equal the sum of the components
^ These are deaths for people with these specific diseases
