  1. *Musculoskeletal pain as defined by a ‘yes’ answer to at least one of our six questions added to the Nordic Musculoskeletal questionnaire. The Brief Pain Inventory describes all types of pain in the previous 24 hours; both measures are on a scale of 0–10, with 10 being the most severe pain or pain that most interferes with daily life. The SF-36 domains are on a scale of 0–100, with a high score indicating a more favourable health state. The FACIT physical, social, and functional well-being subscales are on a scale of 0–28; the emotional well-being sub-scale ranges from 0–24; the FACT-G total score ranges from 0–108, FACT-B 0–144, FACT-ES 0–220; higher scores represent a better QoL.
