  1. Note: P-values based on X2. CI = confidence interval. aOR = adjusted odds ratio
  2. aReference level for categorical variable is the group with largest number of PWH
  3. b Multivariate regression modeling adjusted for demographic characteristics (age, gender, race/ethnicity, housing and employment status), years since HIV diagnosis, HIV risk categories, and AIDS diagnosis
  4. cPatient age is divided by 10, such that one unit increase in age represents the effect of 10 years
  5. dRace/ethnicity was forced into the model that was selected by backward elimination procedure and cross checked with forward selection model selection process
