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

Table 3 Physical activity, pain and function change scores

Change variable	Mean score baseline to 3 months(SD)	Mean score baseline to 6 months(SD)
Change in PASE	15.1 (87.4)	13.5 (86.9)
Change in WOMAC pain	−1.6 (3.2)	−2.1 (3.5)
Change in WOMAC function	−4.5 (10.1)	−6.4 (11.8)

Footnote: Multiple imputed data (combined results from 25 imputed datasets); all change scores calculated by subtracting the score at baseline from the score at three or six month follow up; Higher change in PASE scores indicate higher physical activity at follow up compared to baseline; Negative change in WOMAC pain and function scores indicate reduced pain and higher function at follow-up compared to baseline
