Data from the location identification and verification forms were entered into a password-protected excel spreadsheet. Data was then imported into Stata (version 11.0, STAT Corp., College Station, Texas, USA) for analysis. We calculated measures of central tendency and dispersion for numerical variables and used frequency tables to explore categorical data.
We exported GPS coordinates of suggested PWID locations into an excel spreadsheet. These GPS coordinates and details about location type (i.e. whether or not PWID were interviewed) were entered into QGIS (version 2.6.1 Brighton). Finally, we mapped the locations that were visited graphically to inform outreach service delivery routes. To ensure confidentiality and to safeguard PWID communities included in the mapping, no location details are presented in this manuscript.
