  1. Correlational analyses between each QST parameter (logarithmically transformed, except for CPT HPT, VDT) and the CPM effect’s magnitude were conducted using Pearson’s Correlation Coefficient for measurements at day 1 and day 2. CDT Cold Detection Threshold, CPT Cold Pain Threshold, HPT Heat Pain Threshold, MDT Mechanical Detection Threshold, MPS Mechanical Pain Sensitivity; MPT Mechanical Pain Threshold, PPT Pressure Pain Threshold, QST Quantitative Sensory Testing, TSL Thermal Sensory Limen; VDT Vibration Detection Threshold, WDT Warm Detection Threshold, WUR Wind up Ratio
