* Name-based HIV case surveillance was conducted in Arizona, Colorado, Mississippi, Missouri, and North Carolina (patient names are not reported to CDC); unique identifier (UI)-based HIV case surveillance was conducted in Maryland and Texas; neither name-based nor UI-based HIV case surveillance was conducted in New Mexico and Oregon during the study period.
+ UI-based reporting was implemented during the year preceding the study in Maryland and Texas; 67% of tested respondents in these states had been tested at least once before this policy change. Because of the state reporting policy changes and to avoid small cell sizes in the analysis restricted to the minority of respondents who had never been tested, UI-based reporting and nonreporting states were combined in the non-named reporting category.
Advertisement& -- Fisher's exact test.
@ -- The totals are based on unweighted data from all participants included in this analysis; data do not represent the general population or a weighted average of populations at increased risk for HIV infection.
