Spearman’s rank correlations among pairs of MPA features. Lower triangular correlation matrix: numbers are Spearman’s rank correlations (rho). Superscripts symbols indicates p-values of Spearman’s rank correlations tests: nsp > 0.1; *p < 0.1; **p < 0.01; ***p < 0.001. Upper triangular correlation matrix: Shape and orientation of ellipses are proportional to rho absolute value and direction, respectively.
