The relative risks and 95% CIs of the highest quintiles of the combined intake of vegetables and fruit compared with the lowest quintiles for colorectal cancer are represented as squares and horizontal lines by sex for the 5 ethnic groups. The relative risks were estimated from Cox regression, where age is the time metric, and adjusted for time since cohort entry as strata variabless and age, family history of colorectal cancer, history of colorectal polyp, pack-years of cigarette smoking, BMI, hours of vigorous activity, aspirin use, multivitamin use, replacement hormone use (women), log energy intake, alcohol, red meat, folate, vitamin D, and calcium as independent variables in the log linear model component.
