Figure 2. — Smoking pack-year density curves. Smoking pack-year density curves are presented (A) between African American and White cases, (B) between Japanese American and White cases, (C) between Latino and White cases, (D) between Native Hawaiian and White cases, and (E) across all racial and ethnic groups. The vertical line at 20 pack-years distinguishes the participants who meet the 20 pack-year smoking threshold in the 2021 US Preventive Services Task Force guidelines for lung cancer screening.
