Numbers in bold denote statistical significance at the 0.05 level. Data as reported to the NYC DOHMH by September 30, 2012

NYC HOPWA New York City Housing Opportunities for Persons with AIDS, VL viral load, OR odds ratio, CI confidence interval

^aMatched for race/ethnicity, age at the end of 2011, sex, neighborhood-level poverty, transmission risk, country of origin, concurrent diagnosis (HIV & AIDS), enrollment in other local HIV public assistance programs in 2011, and last CD4 count as of the end of 2010. Neighborhood-level poverty, based on ZIP code at HIV or AIDS diagnosis, represents the percent of residents living below the federally defined threshold for poverty, and is categorized as: 0 to <10 %; 10 to <20 %; 20 to <30 %; and 30 to 100 %

^bRetention in care defined as having ≥2 lab results ≥3 months apart in 2011

^cViral suppression defined as having ≥1 VL ≤200 copies/mL in 2011, among those with at least 1 VL in 2011

^dDurable suppression defined as having ≥2 consecutive VLs ≤200 copies/mL at least 2 weeks apart in 2011, among those with at least 2 VLs in 2011

^eViral rebound defined as having ≥1 VL >200 copies/mL after ≥2 VLs ≤200 copies/mL at least 2 weeks apart in 2011, among those with at least 3 VLs in 2011
