  2. a Unavailable for couples with only one participating partner
  3. b For dyads, we used the response of the HIV positive partner where it was divergent from the negative partner’s response. HIV-positive participants in a past relationship who reported being suppressed at any time in the relationship were classified as suppressed while HIV-positive past-relationship participants who reported that they were virally suppressed “none of the time” during the relationship were counted as not suppressed
  4. c Possible range 1–5; (1 = low, 5 = high)
