Fig. 1 A cohort of singleton pregnancies registered in the Medical Birth Registry of Norway after IVF and ICSI treatment during 1999–2006. αART: assisted reproductive treatment, including IVF and ICSI; βPTD: preterm delivery; χIUFD: intrauterine fetal death; *few pregnancies in this part of the exclusions were represented in more than one category, such as IUFD in a congenitally malformed infant. This means that summarizing the figures is not meaningful.
