Declarations
:
: All methods were carried out in accordance with Finnish regulations. The Ethical Committee of Tampere University Hospital waived the ethical committee evaluation of all retrospective studies utilizing routinely collected healthcare data, and this decision is based on the law of medical research 488/1999 and the law of patient rights 785/1992. In accordance with Finnish regulations (the law of secondary use of routinely collected healthcare data 552/2019), no ethical informed written consent was required because of the retrospective register-based study design, and the patients were not contacted. Both the National Medical Birth Register (MBR) and the Care Register for Health Care have the same unique pseudonymized identification number for each patient. Permission for the use of this data was granted by Findata after the evaluation of the study protocol (permission number: THL/1756/14.02.00/2020).
