Average distance (miles) and time (minutes) by public transportation (per blocked area) between RDS recruits and his/her recruiter by recruit’s recruitment location (N = 348). Although there were 357 peer recruits in the respondent-driven sample, two individuals could not be geocoded, which resulted in the loss of two ties. Additionally, four individuals who were initially eligible to participate in the study were removed from the analysis due to inconsistencies in their self-reported drug use, which resulted in the deletion of seven additional ties. Therefore, the final sample size for recruiter–recruit distance calculations was 348.
