Number of statistically significant phi-correlations per each comorbidity (degree) plotted in migraineurs vs controls. The dashed line represents the regression slope from regressing the number of significant phi-correlations in migraineurs on the controls. Slope = 1.43 (p < 0.001), intercept = 4.04 (p < 0.001), R-squared = 88.6%. The fit shows that the number of significant phi-correlations per comorbidity in migraineurs is explained quite well by the respective number in controls, when the overall increase in morbidity in migraineurs is accounted for. However, visual assessment suggests 3 outliers: F43 (reaction to severe stress, and adjustment disorders), G44 (other headache syndromes), and R51 (headache). This is confirmed by a formal mean-shift outlier test (Bonferroni corrected p-values < 0.001 for all three diagnosis codes)
