*2.4. Data Analysis*

Descriptive data are presented, including range and mean ± SD as appropriate. An unpaired *t*-test on the excursions (ΔT ◦C = threshold temperature–skin temperature) was used to compare the data collected with wired and wireless systems in cats and horses. Friedman's test was used to compare baseline data with NT after opioid treatment as the data are not normally distributed due to "capping" of the peak TT by the cut-off (GraphPad Prism v8). *p* < 0.05 was regarded as significant.
