Depiction of buprenorphine treatment stages and direction of possible transitions. By definition, all participants start follow up when they initiate buprenorphine and are therefore in box 1. If the treatment episode duration is above the retention threshold (e.g., 90 or 180 days), they move to box 2. If they are in box 1 or 2 and stop buprenorphine and are lost to follow up, they move to box 3. If they are in box 1 or 2 and stop buprenorphine and are retained in HIV clinic they are in box 4. Participants can move between being lost to follow up (box 3) and retained in care (4). If after stopping buprenorphine (box 3 or 4) they restart buprenorphine they would return to box 1. Death (box 5) is a competing (terminal) event
