Figure 1.

Number of CT screens and lung cancer deaths averted for risk-based screening strategies screening between ages 55 and 80 years compared with the USPSTF criteria (mean results across the four CISNET models). Risk thresholds corresponding to strategies that yield a similar number of lung cancer deaths averted as the USPSTF criteria: Bach model = 3.4%; PLCOm2012 model = 2.2%; LCDRAT model = 2.1%. CT = computed tomography; LCDRAT = Lung Cancer Death Risk Assessment Tool; USPSTF = United States Preventive Services Task Force.
