Co-segregation of comorbidities in patients with SLE at the community-based registry of Crete. (A) Correlation matrix of various comorbidities from diverse organs and domains. Numbers inside each box represents the Cramer’s V statistic estimated for each pair of comorbidities with values > 0.10 signifying robust correlation. Color intensity corresponds to the chi-squared p-value for each pairwise association. (B) SLE patients were categorized according to the number of physical (none, 1 or 2, ≥3) and mental (none, 1, ≥2) comorbidities as described in the main text. Y axis shows the number of patients with various combinations of physical and mental comorbid disorders.
