Sample size and statistical analysis
viral suppression
Based on prior research in this population [All data were collected on hard copy case report forms and entered in an electronic database with internal logic checks for key variables. Line listing of all variables was performed by printing out a hard copy of the electronic dataset and manually comparing it to the source documents to identify and correct any key-in errors.The primary analysis comparing viral suppression (Participant-level feasibility was measured by the proportion of participants who responded to text messages, the overall proportion of messages receiving a response, and the proportion of clients who asked a question.Participant-level intervention acceptability was assessed through content analysis of qualitative exit interviews. Interviews were audio-recorded, transcribed, and coded by authors GW and FMA. Content analysis using an inductive approach was used to identify emergent themes.
