Declarations

:

: The authors declare no conflicts of interest/competing interests. Authors declare to adhere to the minimum reporting guidelines hosted by the EQUATOR Network when preparing their observational study (STROBE statement).

: This retrospective study, involving human participants, was in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards. The ethics committee of the Centre Hospitalier Universitaire Tivoli, La Louvière, Hainaut, Belgium (Université Libre Bruxelles, Bruxelles, Belgium) approved this study on July 29, 2020 (Number 1362).

: Formal informed consent was exempted by the ethics committee of our hospital due to the retrospective nature of the study and given the risks of awakening a painful past or of calling on a family to process data from a deceased person. No patient expressed opposition to the use of their medical records for research and/or publication purposes. This wish was respected by checking in each computerized medical file whether an objection form was archived in the “clinical research” section.
