Bivariate analysis of characteristics by health status for a sample of HIV-positive adults (n=1,499) enrolled in the SPNS Oral Health Initiative, May 2007–August 2010

^aReference group for independent variable

^bp≤0.05 (p-values based on GEEs controlling for correlation among observations with each of the 14 sites)

^cp≤0.001 (p-values based on GEEs controlling for correlation among observations with each of the 14 sites)

^dp≤0.01 (p-values based on GEEs controlling for correlation among observations with each of the 14 sites)

^eThe range for a healthy CD4 count is 500–1,000 cells/mm³. A CD4 count of <200 cells/mm³ is an indicator of an AIDS diagnosis. Source: Department of Health and Human Services (US).
