Table 5.

Association between HRBS subscale totals for assessments 1 = baseline, 2 = end of active-intervention period, and 3 = end of follow-up.

	Sexual behavior 1	Sexual behavior 2	Sexual behavior 3
Injection-drug use 1	$\widehat{\tau }=0.0098$	$\widehat{\tau }=-0.0729$	$\widehat{\tau }=-0.0480$
	p = 0.7181	p = 0.0255	p = 0.4322
Injection-drug use 2	$\widehat{\tau }=0.0415$	$\widehat{\tau }=-0.0237$	$\widehat{\tau }=0.0110$
	p = 0.2024	p = 0.4691	p = 0.8620
Injection-drug use 3	$\widehat{\tau }=0.0544$	$\widehat{\tau }=0.0508$	$\widehat{\tau }=0.0641$
	p = 0.3703	p = 0.4197	p = 0.2972

Association is measured as concordance via estimates $\widehat{\tau }$ of Kendall’s τ.
