  1. Pain-Related Self-Statements Scale-Catastrophizing (PRSS) score; OMPSQ short-form orebro musculoskeletal pain screening questionnaire, PCS physical component score, MCS mental component score, VAS visual analogue scale
  2. aAll parameters are those that are measured at baseline (within 3 months of sustaining the injury), except for lawyer involvement which was throughout the study period
  3. bReference group are those participants who settled their claim in 0–12 months
