Linear correlation between average cyclic height of the IR-PPG signal and signal integral per minute. The figure includes the entire data set recorded per animal. Both parameters have been transformed to a log2 scale (log-log transformation). Different symbols denote different animals (A1.2 is the second run performed on animal 1). The dashed lines show the 95% confidence interval. Correlation analysis confirmed a significant positive linear correlation between the two parameters (P < 0.05; Pearson’s correlation coefficient 0.837)
