FIG. 7.

Distinctive correlation profiles of patients affected by type 1 diabetes according to disease severity at onset and 12 months later. Graphical representation of the Spearman ρ nonparametric correlation matrix among the study variables. The presence of a significant correlation between two variables is expressed by means of a red (negative correlation) or blue (positive correlation) ellipse, whereas an empty circle refers to a nonsignificant correlation. The color intensity and thickness of each ellipse are proportional to the correlation value (see graphic legend for numeric values). The correlation profile between patients with mild and severe disease at onset and 12 months later is shown.
