Missing values ranged from zero for age to 34 CRC test-specific MD recommendation among those answering “yes” to MD ever recommended CRC screening test.
BE and “no preference” are excluded from chi square analyses. P-values <0.10 are considered statistically significant for purposes of variable selection to the multivariate model.
Test-specific percentages reflect percent of those answering “yes” to general screening question (n=628). P-value reflects comparisons between those ever having specific colon cancer screening test (yes/no) and baseline preferences. Categories are not mutually exclusive; participants could respond “yes” to more than one test.
Test-specific percentages reflect percent of those answering “yes” to general recommendation question (n=616). P-value reflects comparisons between those ever having a physician recommendation for that specific test (yes/no) and baseline preferences. Categories are not mutually exclusive; participants could respond “yes” to more than one test recommendation.
