* CI indicates confidence interval; PPV, positive predictive value; NPV, negative predictive value; AA, African American; AIAN, American Indian or Alaska Native; API, Asian or Pacific Islander. Veterans with multiracial values, veterans who reported Hispanic ethnicity but no or non-AA minority race, veterans with race values reported by observation or proxy after May 2003 and veterans with missing or unknown race values were excluded. ** In self-reported data, Hispanic ethnicity and White or Black race were used to identify respectively Hispanic White or Hispanic Black in this table. Both Asian and Native Hawaiian or Other Pacific Islander in the self-reported data are used to identify Asian or Pacific Islander. | ||||||||
