Gaussian distribution data was analyzed by Pearson correlation analysis. Non-Gaussian distribution data was analyzed by Spearman's rank correlation analysis. r is a measure of the intensity of the effect in Pearson’s correlation coefficient and ρ is a measure of the intensity of the effect in Spearman's correlation coefficient.
