Data are given as percentage of US adult weighted population (95% CI). Demographic characteristics of the study population were compared between those patients with no CVD or CVD risk factors, CVD risk factors alone, and CVD. P values were calculated using the χ2 test. CVD indicates cardiovascular disease.

Other race includes Native American, Alaskan, Pacific Islander, and those who selected multiple races.
