Percentage of responders were assessed in the PAS (N = 70)

[a]A responder is defined as a patient whose score had changed relative to baseline by an amount greater than or equal to the MID; [b]SEM was calculated using Cronbach's alpha for internal consistency reliability; [c]Reduction in tumor size ≥30% was used as the anchor for MID thresholds
