Pearson’s Correlation between QST Response and Clinical Factor

	CPTh	HPTh	CPTol	HPTol	HPDur
MED	0.15	−0.36^*	0.08	0.02	0.11
DOT	−0.08	0.02	−0.07	−0.14	0.03

MED: daily morphine equivalent dose; DOT: duration of opioid treatment; DOP: duration of pain; CPTh: cold pain threshold; HPTh: heat pain threshold; CPTol: cold pain tolerance; HPTol: heat pain tolerance; HPDur: duration of tolerance to supra-threshold heat pain stimulation. All values are Pearson’s correlation coefficients.
