No incidence differences between pre- and postimplementation periods were statistically significantly different. See Figure 1.
Other and unknown sex were excluded (no HIV cases).
No recent cases; in bootstrapping procedure, the proportion of HIV-positive cases classified as recently infected was sampled from a truncated normal distribution with .
Combined category consisting of American Indian or Alaska Native, more than one race, other race, and unknown race/ethnicity.
US territories and unknown region were excluded (no HIV cases).
