Abbreviations: APR, adjusted prevalence ratio; CI, confidence interval; DHHS, Department of Health and Human Services; NHAS, National HIV/AIDS Strategy.

Models included an interaction between retention measure and age group, and adjusted for sex, race/ethnicity, HIV risk factor, first CD4 cell count in the year, use of ART for >6 months during the year, calendar year, and cohort as time-fixed covariates.

Bold signifies adjusted prevalence ratios with p-vale <0.05.
