*Some cells do not equal 100 % due to missing data: 18 % had missing income data, 5 % had missing employment status, and < 1 % of values of other variables were missing.
†Numeracy is measured by an eight-item scale13,14
‡Summary knowledge score was calculated as the mean number of correct answers of a series of nine colorectal cancer knowledge questions (see methods). A higher score = higher summary knowledge.
