Fig. 5. The correlation coefficient matrix showing the relationships between the pathophysical indexes and hemodynamic indexes in segmented artery and tissue area. (A) The lower left triangle with the color scale indicates a correlation coefficient between indexes, while the upper right triangle with the gray scale indicates the significance of the correlation coefficients. Pearson's correlation analysis was used, and the gray scale only displays statistically significant p-values. (B) Summary of correlation coefficient and p-value (*, Correlation is significant at the 0.05 level; **, Correlation is significant at the 0.01 level).
