Study I aim: To develop prediction models for individual pregnancy-related risks in mono- and dichorionic twin pregnancies, and evaluate the risk of adverse obstetric outcomes, i.e., spontaneous abortion, intrauterine fetal demise, neonatal death and preterm birth, in a large unselected nationwide cohort of twin pregnancies.
Study II aim: To estimate the risk of miscarriage after fetal reduction or selective feticide in multifetal pregnancies and describe the obstetric outcomes in a large national cohort.
Study III aim: To evaluate how women perceive and are psychologically affected by being pregnant with twins, assessed in both complicated and uncomplicated pregnancies.
