Prepared by the Bureau of HIV/AIDS Prevention and Control with data reported to the NYC HIV Surveillance Registry as of September 30, 2014

RR relative risk, calculated using Generalized Estimating Equations (GEE). CI confidence interval, MCS mental component summary. Baseline: based on the CCP provider-conducted intake assessment at client enrollment. Post-baseline: based on the latest CCP provider-conducted reassessment in the year of follow-up

^aClients enrolled in the NYC CCP between December 1, 2009 and March 31, 2013, matched to the NYC HIV Surveillance Registry, and living 12 months after the date of enrollment

^bNewly diagnosed: CCP clients who were diagnosed in the 12 months prior to their CCP enrollment window (defined as the 31 days leading up to and including date of enrollment)

^cPreviously diagnosed: CCP clients who were diagnosed greater than 12 months prior to their CCP enrollment window (defined as the 31 days leading up to and including date of enrollment)

^dEiC, or engagement in care: ≥2 CD4 or viral load (VL) tests ≥90 days apart, with ≥1 test in each half of the 12-month period

^eVLS, or viral load suppression: viral load (VL) ≤200 copies/mL on most recent test in the second half of the 12-month period. Clients who did not have a VL test reported during the second half of the 12-month period were categorized as unsuppressed

^*Using a Chi square test, at the 95 % confidence level, there was a significant difference in post-enrollment outcomes between these subgroup(s), excluding those groups with missing data on this variable

^†At the 95 % confidence level, this subgroup's RR was significantly higher than the RR(s) of some other subgroup(s) with non-missing data on this variable

^‡At the 90 % confidence level, but not the 95 % confidence level, this subgroup's RR was significantly higher than the RR(s) of some other subgroup(s) with non-missing data on this variable
