Screening and Baseline measurements as well as treatment start can be performed on the same day. In this case, all measurements are only performed once. The baseline should be maximum 4 weeks before the treatment start; otherwise, baseline measures should be repeated (without ESIT-SQ, TSCHQ, BFI-2, ATAQ, electrophysiological measurements). ^aDeclaration of consent (ICF) can be digital for the pre-screening. ^bOnly for participants who were allocated to a single or combinational treatment with HA. ^cBlood samples can be taken at any time point before treatment start
