The investigation involved the TRANSPOSE project initiated in September 2017 and included 25 associated partners from 15 European countries (https://www.transposeproject.eu). Participants/stakeholders reported complications (serious and non-serious) for blood, plasma, hematopoietic stem cells, gametes, embryos and tissues. Overall complication rates are presented in Table 1 of the manuscript and below. Specific types of complications are presented for whole blood and stem cells in manuscript Tables 3 and 5.

Three countries provided the combined data forwhole blood and plasmapheresis. These are presented in the third row as ‘unspecified type of blood donation’
Time to detection: 
No time to detection was provided but given the diverse set of donation types and complications it is likely that some were proximal to donation and some developed over time.
Alerting signals, symptoms, evidence of occurrence: 
Highly diverse and dependent on donation and complication type.
Demonstration of imputability or root cause: 
For the purpose of this report, all adverse reactions reported by participants were included regardless of level of imputability. However, it is clear from the types of complications reported that most are likely to be directly linked to donation.

Expert comments for publication: 
The authors conclude that in Europe, donor complications are rare but are likely to be underreported. Complication reporting is non-standardized. The authors advocate a standardized donor vigilance system.
