Source/Notes: SOURCE Authors’ analysis. NOTES The average is for all risk groups (explained in the text). In 2015, 6.82 million US adults were eligible for annual LDCT screening, as explained in the text. Whiskers indicate 95% confidence intervals. The interval bounds correspond to the people in a group at the 2.5 and 97.5 percentiles. For example, for people in the highest risk group over a lifetime horizon, the person at the 2.5 percentile gains 0.032 life-years (3,200 life-years per 100,000 people), whereas the person at the 97.5 percentile gains 0.0915 life-years (9,150 life years per 100,000 people).
