A scatter plot of hemoglobin saturation and fluorescence redox ratio for the final four animals in this study for which more detailed measurement of fluorescence redox ratio was obtained. It can be seen that individual animals show strong linear correlations (average correlation of 0.9), but that the overall correlation is less strong, yielding an overall correlation coefficient of 0.5.
