*Adjusted Relative Risk using Cochran-Mantel-Haenszel methods: RR adjusted for race for knowledge outcomes; and age group (median split; median age = 61.5 yrs.) for receipt of screening.

‡Relevant screening tests include fecal occult blood testing (or stool test kit), flexible sigmoidoscopy, and colonoscopy.

£ Currently screened defined as receiving fecal occult blood testing within the last year, flexible sigmoidoscopy within the last five years, or colonoscopy within the last 10 years.
