Plans to promote participant retention and complete follow-up {18b}
Participant retention is expected to be high because the study visits are incorporated within routine outpatient care and no additional invasive procedures are necessary. Retention will be improved by participant calls every 2 weeks performed by the study team. For participants who discontinue or deviate from the intervention, the study team will try to continue the study following the protocol of the control arm. The documentation of all subsequent visits should still be pursued.
