1 Repeat Positive: eligible study individuals who had additional confirmatory Western blots (WB) tests obtained ≥90 days after initial diagnosis. Each positive WB obtained after ≥90 days was considered a separate result. No Repeat Positive: eligible study individuals who had confirmatory WB tests all obtained <90 days after initial diagnosis. All considered a single test for analysis purposes.
2 Number (%) out of 8,677 study eligible individuals at end of 2006 who had a report to eHARS of either a CD4+ T-cell count or viral load in each 6-month interval from 2007-2009.
3 RR indicates relative risk. CI indicates confidence interval.
4 “Not in care” defined as having no viral load or CD4 T-cell count reported during 2007-2009; “Sporadic care” defined as having either a viral load or CD4+ T-cell count reported during at least one six-month period but not for all six periods; and “In care” defined as receiving a viral load test or CD4+ T-cell count at least once during each six-month period of 2007, 2008, and 2009.
