Table 3 Prevalence of lung cancer among 100,000 smokers and predicted lung cancer deaths in low-dose CT, chest X-ray, and no screening scenarios with different age inclusion criteria

From: Mortality outcomes of low-dose computed tomography screening for lung cancer in urban China: a decision analysis and implications for practice
