2. Materials and Methods
2.1. Study Design and Participants
2.2. Outcome- and Predictor Variables
“Rate your pain for the low-back within the previous 4 weeks (0–10, where 0 is no pain and 10 is worst imaginable pain).”
“How often during the previous 4 weeks have you…”:
- (a)
“awoken during the night and having trouble going back to sleep?”- (b)
“been feeling exhausted when waking up?”- (c)
“been feeling tired during the day?”
2.3. Covariates
2.4. Ethics
2.5. Statistics
