  1. NRS: Numeric Rating Scale, SF-36: Short Form 36, MPI: Multidimensional Pain Inventory, HADS: Hospital Anxiety and Depression Scale, CSQ: Coping Strategies Questionnaire. ES: Effect Size, SRM: Standardized Response Mean. p: Type I error of the modified Jacknife test comparing two ES or two SRM. r base: bivariate Spearman rank correlation of the baseline scores, r diff: bivariate Spearman rank correlation of the effects (raw score differences baseline → follow-up)
