Matrix shows non-parametric Pearson correlation coefficient r values. Significant correlations are defined as r > 0.5, p < 0.05; r = 0.5–0.6 are weak correlations, r = 0.6–0.7 are moderate correlations, r = 0.7–0.9 are strong correlations, and r > 0.9 are very strong correlations. All correlations of r < 0.5 had a p value >0.05. The red colour denotes positive correlations, while blue denotes negative correlations; the darker the colour, the stronger the correlation.
