Panel A. For each quintile of competing mortality risk,
quality adjusted life year (QALY) gains (y-axis) by baseline lung cancer risk
(x-axis) under base-case assumptions. Baseline lung cancer risk is by percentile
from 0–100. Incremental QALY gains from LDCT screening decline as
competing mortality risk increases.
Panel B. Quality adjusted life year (QALY) gains for highest
(5th) quintile of competing mortality risk, by baseline lung
cancer risk (x-axis).
Panel C. Quality adjusted life year (QALY) gains when
excluding persons in highest (5th) quintile of competing mortality
risk, by baseline lung cancer risk (x-axis).
