Table 1.
Estimated marginal means of changes in the WOMAC Index from baseline to 12 weeks and to 12 months, standard error, 95% CI, mean difference based on the marginal means and significance for the mean difference. Therapy, gender, and patients’ expectations for therapies received as fixed factors and WOMAC-A (pain), WOMAC-B (stiffness), and WOMAC-C (functional limitations), all three at baseline, as covariates.
