It is very uncertain whether interventions for increasing immunosuppressant medication adherence changes self‐reported adherence (proportion) compared with standard care (very low certainty).
It is very uncertain whether interventions for increasing immunosuppressant medication adherence changes proportion of immunosuppressant trough concentration levels at target compared with standard care (very low certainty).
