Research aim: The aim of this study was to assess whether and how it would be possible to carry out a future definitive RCT of the Wrapped intervention. Participants (n=230) were recruited via a web-based STI self-sampling provider. Methods for processing the data: Data was collected using REDCap (web-based data management system) and downloaded to SPSS statistical package for data cleaning and computing/recoding variables as required for the analysis. Instrument- or software-specific information needed to interpret the data: Analysis performed using International Business Machines Corporation (IBM) Statistical Package for the Social Sciences (SPSS) version 28. People involved with sample collection, processing, analysis and/or submission: All analysis (except cost analysis) performed by the lead author (KN) and checked by study statistician (NS). Cost analysis performed by co-author LJ.
