QST thermal measures comparing CTS participants and control data. Boxes represent the interquartile range, the centre line the median. The black upper dotted line represents + 1.96z, the bottom dotted line - 1.96z. Scores between the two are interpreted as normal, those above as gain of function and below as loss of function. Significance is denoted as * at the 0.05 probability level; ** at 0.01; *** at 0.001. Cold detection threshold (CDT); cold pain threshold (CPT); heat pain threshold (HPT); thermal sensory limen (TSL); warm detection threshold (WDT)
