Table 5 The association between change in physical activity level and pain and function at 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 pain at 6 months model; Gold = Adjusted physical function at 6 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. Regression coefficients shown are rounded to two decimal places and a score of − 0.00 is used to indicate a very small yet negative confidence interval coefficient. * = 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
