¹Interaction P-value for the test of whether the regression coefficient for CD4 < 500 is different than that for CD4 ≥ 500
^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
^bn = 206 had missing CD4 values
^cn = 2211 had missing CD4 values
^dAdherence measured in 10% increments of the VAS
