aOAK: Osteoarthritis of the Knee Self-Management Program. SF-36: Short Form 36 version 1 questionnaire; WOMAC: Western Ontario and McMaster Universities Arthritis Index. bPreintervention values were the same in both groups when the baseline value was used as a covariate. 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) differences in changes between the groups at each time point. cP < 0.05 for baseline to 6 months. |
