  1. 1Interaction P-value for the test of whether the regression coefficient for CD4 < 500 is different than that for CD4 ≥ 500
  2. aLinear regression of Log VL on adherence, adjusted for age, sex, and study indicator, stratified by CD4 count level in the criminal justice and routine care samples
  3. bn = 206 had missing CD4 values
  4. cn = 2211 had missing CD4 values
  5. dAdherence measured in 10% increments of the VAS
