Figure 2

(A) Spearman correlations between all imaging parameters. Significant correlations (p ≤ 0.05) are indicated with ellipses with the shape of each ellipse reflecting the direction and strength of the correlation. Positive correlations are described with ellipses directed from the lower left to the upper right and negative correlations are described with ellipses directed from the upper left to the lower right. Strong correlations are described with thin ellipses and weak correlations with thick ellipses. Non-significant correlations are indicted with blanks. (B) Scatter plot of the first and second principal components by clinic based all imaging parameters in n = 33 subjects; the centroids were not significantly different (p = 0.73).
