  1. NRS: Numeric Rating Scale, SF-36: Short Form 36, PCS: Physical Component Summary, MCS: Mental Component Summary, MPI: Multidimensional Pain Inventory, HADS: Hospital Anxiety and Depression Scale, CSQ: Coping Strategies Questionnaire. m: Mean, s: Standard deviation, ES: Effect Size, SRM: Standardized Response Mean. MCID: Minimal Clinically Important Difference in units of the ES or the SRM (see in Methods, Analysis), ICC: Intraclass Correlation Coefficient (obtained by literature review: i.e. the instruments' manuals). Scaling: 0 = no pain, 10 = most pain for the pain NRS; 0 = worst, 100 = best for all instruments' scales
