Table 4 The association between change in physical activity level and pain and function at three 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 pain at 3 months model; Gold = Adjusted physical function at 3 months model
  2. Footnotes: Multiple imputed data; multiple linear regression adjusted models selected via backwards elimination holding treatment arm and change in physical activity in the model. * = statistically significant β coefficient P < 0.05; ** = statistically significant β coefficient P < 0.01. Higher WOMAC scores indicate higher pain and worse function. 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
  3. Abbreviations: β  Unstandardized coefficients, BMI Body Mass Index; CI=Confidence Interval, PASE  Physical Activity Scale for the Elderly, PHQ8  Personal Health Questionnaire, WOMAC Western Ontario and McMaster Osteoarthritis Index
