  1. aOAK: Osteoarthritis of the Knee Self-Management Program; TUG: Timed Up & Go Test. bPreintervention values were the same in both groups when the baseline value was used as a covariate. cP < 0.05. Preintervention (baseline), postintervention (8 weeks) and 6-month values were calculated using repeated-measures analysis of covariance with the baseline value of the dependent variable as the covariate. Data are estimated marginal means (SEM) with the mean (95% CI) difference in changes between the groups at each time point.
