Lymph node status (n = 28 237) | ||

CAD = computer-aided detection; OR = odds ratio.
Adjusted for age, race or ethnicity, rural vs. urban residence, median income of elderly residents within the same ZIP code, time since previous mammogram, use of CAD on the previous examination, presence of stable and unstable comorbid conditions, digital vs. film mammography, year of examination, and SEER (Surveillance, Epidemiology and End Results) region. Sample sizes differ from the total number of invasive cancer cases (n = 36 270) because of missing or unknown stage, size, or node status or missing covariates.
