For the purpose of this review, there is a specific focus on antenatal management of DCDA twin pregnancies. • The antenatal period extends from the start of pregnancy to the onset of labour |
Interventions | • Any intervention focusing on the antenatal management of DCDA twin pregnancies |
Comparator(s), Comparisons, and (key) Content | • Any comparator or comparison • Key clinical practice guideline (CPG) content of interest is DCDA twin pregnancy antenatal management (including general twin pregnancy recommendations) |
