Table 3:

Relative risk (RR) and odds ratio (OR) estimates for detected cases among persons experiencing homelessness or who use drugs (n=385) by risk status (homelessness and illicit drug use), sex and age group (in years). For each variable level, total case counts as well as case counts by period (pre-peak, peak and post-peak) are presented. RR and OR used here are as defined in Worby et al. [16].

Variable	Number of cases				RR^a (95% CI)	OR^b (95% CI)

Estimates are not computed for groups with fewer than ten cases in total.
