Correlogram of the iron forms measured in this study and grouped by diagnosis. The ellipse eccentricity and color intensity are proportional to the Spearman’s correlation coefficient for a specific pair of iron forms (see also scale bar at the bottom). Left panel refers to the control group (N = 11, after outliers were removed as explained in the Materials and Methods section) while the right panel refers to the patients group (N = 18, after outlier removal). Correlograms which are not statistically significant, i.e. p-value > 0.05, are crossed. For those correlograms with p-value < 0.05, the correlation coefficient is reported in the respective squares. Letters are used to facilitate the comparison between pairs of variables.
