Mean (SD) predicted benefits from 5 models for 41 selected (of 120) consensus programs (both sexes combined).

Percentage of cohort screened, numbers of CT screens, lung cancer deaths avoided, and life years saved are all normalized to cumulative counts per 100,000 people in the cohort at age 45 (including non-smokers and persons not screened), followed to age 90. See Table S2 in File S1 for complete list of 120 consensus programs identified from the 576 programs evaluated.
Frequency, A = annual, B = biennial (every 2 years), T = triennial (every 3 years); Start Age, Stop Age, PY = minimum pack-year, YSQ = maximum years since quit.
NNS, Number (people) needed to screen (ever) to prevent one lung cancer death.
∧Percent of cohort that received at least one screen; eligible individuals varied across programs.
** Numbers of lung cancer deaths avoided and life years saved were first calculated per model, comparing each model to its own results for lung cancer deaths in the no-screening arm. Shown are averages across models. The average (across models) number of lung cancer deaths in the no screening scenario was 3719 (SD 820).
Average Coefficient of Variation (CV) calculated as the average of (SD/mean) for each program in the table. Lower values indicate less dispersion of estimates from the models for that endpoint, across the selected consensus programs.
