Notes: Column percentages presented; percentages may exceed 100% due to rounding.
a
A total of 337 participants provided a testable specimen. One participant with missing drug use data was excluded from all analyses.
b
An undetectable HIV-1 RNA result indicates that no HIV-1 RNA was detectable in the DBS specimen.
c
Individuals categorized in the ‘≤832–1,499 copies/mL’ group include individuals who had a qualitative (≤832 copies/mL) DBS HIV-1 RNA result and a quantitative DBS HIV-1 RNA result that ranged between 833 – 1,499 copies/mL.
d
Chi-square test.
e
Denominators vary due to missing data.
