^a Months 0–12 are FBG1 data. Months 13–24 are FBG2 data
^b Viral load test frequency is guided by the MOH Treatment Guidelines. Other tests are done if clinically indicated
^c Facility visits could be either scheduled ARV collections or unscheduled visits for other needs. Included ARV collections for all DSDM clients, even if collected by a community/group member on behalf of the client – and costs of pharmacy and nurse time were split between group members
^d DSDM events count excluded the ARV pickups from facilities which were counted as facility visits
^e FBG support groups could occur in community or at facilities, but are all labelled here as DSDM events
