Line width reflects the Pearson correlation coefficient, while line color reflects the nature of the correlation (positive or negative) and the associated p value. In the matrix of pairwise comparisons, Pearson correlation coefficients are indicated using a color gradient. ***p < 0.001, **p < 0.01, *p < 0.05.
