Note: On an annualized basis, we will recruit an estimated 6,500 smokers for Wave A and anticipate that approximately 4,000 (62%) of those will participate in the Wave B follow-up. We anticipate maintaining a total smoker sample size of approximately 4,000 through continued follow-ups and sample replenishment at each of the remaining waves (Waves C, D and E). Approximately 2,500 nonsmokers will be recruited for the Wave A survey and we anticipate that 2,000 (75%) of those will be retained for the Wave B follow-up. A sample of approximately 2,000 nonsmokers will be maintained through continued follow-ups and sample replenishment at each remaining wave (Waves C, D and E). We anticipate that approximately 25,000 individuals annually will be screened to yield the initial Wave A sample of 6,500 smokers and 2,500 nonsmokers.
