Note: Boldface indicates statistical significance (p<0.001). NLST results were derived using individual data from the original dataset.
ARR, absolute risk reduction; NA, not applicable.
Time to prevent 1 lung cancer death per 2000 people screened with LDCT.
Time to prevent 1 lung cancer death per 1000 people screened with LDCT.
Time to prevent 1 lung cancer death per 500 people screened with LDCT.
The upper limit of 95% CI does not exceed 12.0 years due to censoring at 12 years of follow-up.
