  1. aCited as “R. M. Kaplan, 1999, personal communication” in text. For the purpose of this analysis, we assume that the methodology described in [49] was used in this paper
  2. b“Utility values for the various model states were also drawn from a variety of literature sources [2027].” Fiscella was one of these sources. We assume it is for QALYs associated with quitting smoking. Notes that sensitivity analyses were conducted for utility values, but not clear if sensitivity analysis done specifically for utility values associated with quitting smoking
