Declarations
:
: Samples are the same as in Zieger and Utz [CitationRef removed]. All samples were collected with informed written consent. They were reversibly anonymized, to permit the donors to exert their right to withdraw their sample at any time. The Institute of Forensic Medicine, University of Bern, obtained the samples under an arbitrary number. The written consent documents with the names of the donors remained with the Red Cross. All documents distributed to the donors upon sampling were submitted to the responsible cantonal ethical committee and approval was obtained.
: The authors declare no competing interests.
