NoCD no case detection, S1a CDQ ≥ 17 points among all patients, S1b screening spirometry (with bronchodilator) all patients, S1c CDQ + screening spirometry (with bronchodilator) all patients, S2a screening spirometry (without bronchodilator) among symptomatic patients, S3a CDQ ≥ 19.5 points among ever smokers aged ≥ 50 years, S3b CDQ ≥ 16.5 points among ever smokers aged ≥ 50 years, S3c screening spirometry (without bronchodilator) among ever smokers aged ≥ 50 years, S3d CDQ + screening spirometry (with bronchodilator) among ever smokers aged ≥ 50 years. The solid blue line indicates the efficiency frontier, and the grey dashed line indicates the WTP threshold ($50,000 per QALY gained). The highest value scenario using the efficiency frontier approach is highlighted in red”. Johnson et al. (2021)
