Low, Medium, and High Temperatures from calibration are in °C. Pearson values represent the mean of within-subject correlations for the listed values for each group. Chi–Square tests were used to compare categorical variables (*) and Mann–Whitney U-tests used to compare continuous variables between groups. There were no significant group differences in any variable.
