Table 4.

Estimated regression coefficients (Est.), their standard deviations (Std.), total rate of missing information (λ̂), rate of missing information due to the class variable (λ̂^B|A), and rate of missing information due to non-response in the items (λ̂^A). Model 1 represents the LCR with race/ethnicity as a covariate, while Model 2 includes the mammography history as an additional covariate (Early Stage class is the baseline).
