Supplementary file 1_Corridor-based relative severity assessment of the canine anaesthetic course.docx

This is an exploratory secondary analysis of existing data, with no a priori power calculation. Under the selected bands, the calculated score changed across the recorded anaesthetic course: low while awake, rising at the documented propofol induction, maintained, and resolving on recovery. The dominant departures were hypotension, hypothermia, and mild hypercapnia, sometimes coinciding with a single animal, though their magnitudes are band-dependent.

Corridor RELSA produced a number that changed across the recorded anaesthetic course and represented bidirectional departures as a single continuous score. The between-protocol comparison is not interpreted as evidence about the protocols because the verdict it returns depends on the variable panel being scored. The approach is a domain extension and a small refinement of the human-ICU corridor concept.</p>
