Data are presented as mean (SD) for untransformed data (CPT, HPT, VDT) and retransformed mean for log-tranformed data. P-values reflect statistics carried out on log-transformed data as appropriate comparing pre- and postoperative data (pre post), healthy controls with CTS patients pre-surgery (HC-pre) and healthy controls with CTS patients post-surgery (HC-post). P-values that were significant following Benjamini-Hochberg correction are highlighted in bold. 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; TSL = thermal sensory limen; VDT = vibration detection threshold; WDT = warm detection threshold; WUR = wind-up ratio.
