aAdjusted for age, sex, SES, LHIN, total ADG score, usual provider continuity index, repeat FOBT after index positive FOBT, and prior colonoscopy. Each covariate was entered in the multivariable Poisson model as indicated in Table 1.
bRevision of standardized reporting of positive FOBT result to PCPs. Implemented February 1, 2010.
cReporting of positive FOBT result directly to participants. Implemented October 1, 2010.
dNot statistically significant.
