NRT = nicotine replacement therapy; OTC = over the counter, ℞ = prescription.
↵4-150 Changes in parameters noted as a multiplier; 4-150baseline represents the values of the parameter across age and sex strata multiplied by the number to achieve the result listed.
↵4-151 Measured in average years of life gained for an individual smoker.
↵4-152 The weighted average is the average of the values across age and sex strata adjusted to the American adult smoking population. These numbers are provided for reader reference; the analyses were performed using adjustment of each of the strata by the multiplier listed.
↵4-153 The threshold value is the value of the parameter at which the life expectancy is equal in both the ℞ and the OTC scenarios.
