I hope this is just a short after play, but the researchers have written to NEM and asked them to reconsider. They raise 15 issues with NEM's decision to remove the ethical approval of their study. The letter will be part of the agenda on a meeting in NEM tomorrow. Minutes from the meeting is expected in August.
The letter is available in English translation in this blog post by Nina E. Steinkopf:
Controversial ME study was stopped; The researchers are not giving up
quote from letter:
In the same way as with all other research, there may be doubts about the researchers’ wishes and motivations. This applies in particular to research on controversial topics such as ME, climate, vaccines, salmon, wolves, opioids, etc. An ideal of full confidence in research is an important ideal that should be pursued, but which cannot be used as a premise for conducting studies in controversial fields.
