FIG. 2.

Correlation matrix representing relationships between phenotypic variables analyzed in tolvaptan-treated CC mice. Phenotypic variables are plotted against themselves and other variables on the x- and y-axes. Shading intensity of the corresponding squares reflect the Spearman correlation coefficient, r. Diagonal lines within the squares reflect the directionality of the correlation (ie, lines going from bottom left corner to top right corner indicate positive correlation; lines from top left corner to bottom right corner indicate negative correlation).
