Graphs of predicted values for 12-week pain intensity outcome based on race and Baseline Pain Catastrophizing Scale (PCS) score and on race and Baseline PSEQ score. The blue lines represent Black participants, and the red lines represents non-Hispanic White participants. (A) The regression equations to predict 12-week pain intensity from the baseline PCS were 1.80 + 0.14 × PCS for Black participants and 3.22 + 0.006 × PCS for non-Hispanic White participants. (B) The regression equations to predict 12-week pain intensity from the baseline PSEQ were 6.56–0.04 × PSEQ for Black participants and 6.76–0.07 × PSEQ for non-Hispanic White participants.
