Is there evidence that GET is harmful?

There's a thread dating from four years ago about GET and whether there is good evidence it is actually harmful. I was wondering whether there has been any new evidence since then. (old thread is here: https://s4me.info/threads/2-day-cpe...at-get-is-harmful-and-is-it-a-biomarker.5622/)
I apologise for the odd title but it was the only way I could get the posting of the comment to work. (Title now edited)
