  1. aModel 1: Model includes an intercept, an indicator of HAART or HAART-naïve group (Short-Term HAART Effect) and the time from index visit (Change per 6 months).
  2. bModel 2: Model 1 + age, ethnicity and education level.
  3. cModel 3: Model 2 + income, employment and health insurance.
  4. dModel 4: Model 3+ CD4+ cell counts and viral load.
  5. eModel 5: Model 4+ number of symptoms, outpatient visits, hospitalizations and medication, AIDS history and clinical depression. Interactions between HAART and time from index visit were not statistically significant for all models.
