Notes. p < .01 between pretreatment and 36 weeks; Δ = model-based change from baseline to week 36;
the high-pain group demonstrated significantly less change than the low-pain group from baseline to week 36; BDI-II, HRSD, and Role-Emotional models are calculated using Weighted Generalized Estimated Equations methods; Role-Physical and Pain models are calculated using Generalized Estimated Equation methods.
