Declarations
:
: The study followed the principles of the Declaration of Helsinki (World Medical Association, 2018). Ethical approvals were given by the Swedish Ethical Review Authority (No. 2019–03626 and 2020–04657). When pregnant women are registered at antenatal care, they are informed on the purpose of the Swedish Pregnancy Register provided via a poster, and the possible use of register data in future research. Information includes the voluntariness of contributing with data to the quality register and the option to opt-out. Hence, by accepting to be a subject in the register, the women provide consent to participate in research based on the register data. No additional informed consent was sought prior to inclusion in the present study.
