Table 1 Subject baseline characteristics - mean pain scores and DCE parameters of subjects in each group

From: With a biomechanical treatment in knee osteoarthritis, less knee pain did not correlate with synovitis reduction

  Controls (N = 63 randomised, 62 attended 6 week visit) Brace group (N = 63 randomised, 58 attended 6 week visit)
Variable N in analysis Baseline ean (SD) 6 week visit mean (SD) N in analysis Baseline mean (SD) 6 week visit mean (SD)

  1. aNumber of observations for KOOS and VASNA are less than the number attending week 6 visit due to incomplete questionnaires
  2. bDynamic data model error prevented the use of one RElate observation
