5. Figure 3
Association between screening patterns and death from CRC, KPNC and KPSC 2006–2012. Estimates derived from 3 separate conditional logistic regression analyses of screening histories on risk of CRC death were adjusted for race and ethnicity, SES, Charlson score, and PCP visits. Supplementary Table 4 presents sample sizes. *This estimate is for all failures to screen combined. The model included a separate indicator for failure to follow-up; being up to date in screening was the reference group. †This estimated the association between being up to date with screening compared with a reference that consisted of all screening process failures.
