Table 1.
(A) Demographics of study populations, both those who tested positive and the total population for the ethnic distribution of veterans being tested. Only those tested in patient care areas serving veterans specifically were included in the total population. (B) The average and standard deviations for the CT/CN values for all tested patients including African American patients and others
