Table 6 The association between change in physical activity level and treatment response at three and six months follow-up

From: Change in physical activity level and clinical outcomes in older adults with knee pain: a secondary analysis from a randomised controlled trial

  1. Key: White = Unadjusted Models; Blue = Adjusted OMERACT-OARSI treatment response models
  2. Footnotes: Multiple imputed data, multiple logistic regression adjusted models selected via backwards elimination holding treatment arm and change in physical activity in the model. Higher WOMAC scores indicate higher pain. * = statistically significant OR P < 0.05; ** = statistically significant OR P < 0.01. Higher PASE score indicates higher level of physical activity, #absolute change in PASE calculated by subtracting the baseline score from the score at three months. Higher PHQ8 depression scores indicate worse depression
