- Fixed effects in models are presented with pain intensity (NRS) as outcome
- Model 1 is the estimated change trajectory without the effect of treatment advice. Model 2 includes the effect of treatment advice, where the effect of the Adjust activity is presented first followed by the added effect of the Stay active advice
- A first-order polynomial function was used including the linear term (Day) describing a decrease in pain intensity over time (negative values)
