Compliance with ethical standards

:

: All authors declare that they have no conflicts of interest.

: All procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the 1975 Declaration of Helsinki, as revised in 2008.

: Each center obtained local ethics committee approval before enrollment. Because there was no identification of the patients for whom data were retrieved, informed consent by the patients was waived.
