-
↵4-150 p<0.05;
-
↵4-160 p<0.01 for difference of first follow up assessment compared with baseline (paired ttest); no significant differences between second follow up and baseline assessments;
-
↵4-151 p<0.01 for difference in BoNT/A effect size between cranial and cervical dystonia (unpaired ttest); BoNT/A effect size=(first follow up score–baseline score)/1 SD of baseline scores; PF=physical functioning; SF=social functioning; RP=role-physical; RE=role-emotional; MH=mental health; VIT=vitality; BP=bodily pain; GH=general health; UI=utility index; VAS=visual analogue scale.
