Categorical variables are expressed as number and continuous variables are expressed as mean (SD). ICD, International Diagnosis Code; USD, American dollar; MCS, mental component score; PCS, physical component score; VR, veteran's rand; DASH, The Disabilities of the Arm, Shoulder and Hand questionnaire. Higher scores for DASH indicates more disability. Higher scores for VR-12 indicates higher level of health.
