Spearman correlation analysis of correlation between ceramides. The color of the square shape represent the value of the correlation coefficient. The darker the color of the square, the larger the absolute value of the correlation coefficient; the color of the square corresponds to the value of the correlation coefficient on the color scale. The main diagonal of a correlation matrix represents the correlation of each variable with itself, which is shown in gray and described as corresponding to a coefficient of 1.*P < 0.05, **P < 0.01, ***P < 0.001.
