PR corresponds to the increase in ARV use for each 3-year increase in interview year (ie, 2009–2012 or 2012–2015); models include participant’s personal network size, region, year, the covariate, and the interaction between the covariate and year.
Adjusted models are adjusted for sex, race/ethnicity, current age, and current insurance in addition to the variables included in the unadjusted models.
Hispanics/Latinos can be of any race.
Includes those reporting American Indian or Alaska Native, Asian, Native Hawaiian or Pacific Islander, other race, or multiple races.
Midwest and West: Chicago, Denver, Detroit, Los Angeles, San Diego, San Francisco, Seattle; Northeast: Boston, Nassau-Suffolk, Newark, NY, Philadelphia; South and Territories: Atlanta, Baltimore, Dallas, Houston, Miami, New Orleans, San Juan, D.C.
