  1. ICC: intra-class correlation; SEM: standard error of the mean.
  2. †For assessment of technique repeatability, after an initial set of measurements was acquired, the animal was removed from the set-up, placed back on the set-up, and the measurements were repeated.
  3. ††Single-measurement, absolute-agreement, 2-way mixed-effects model.
  4. †††Bland–Altman analyses.
