Ethics approval and consent to participate

: Advice was sought from the Ethics Committee of Université Catholique de Louvain and Cliniques Universitaires Saint-Luc. Following their advice, ethical approval and consent to participate were deemed unnecessary for this study. Indeed, our study did not fall within the scope of the Belgian Law of 7 May 2004 on Human Experiments, as it did not involve any patients nor patients’ relatives, nor did it require that patient data be shared with the researchers. However, the ethics committees of the 11 participating neonatal care units were informed of the study by their respective representatives in the study.
