Migraine and Complex Regional Pain Syndrome: A Case-Referent Clinical Study

Figure 1

Age distribution among the different cohorts. Age distribution was normally distributed among all cohorts (D’Agostino & Pearson omnibus normality test). There was no statistically significant intermean difference in age among the different cohorts (, ANOVA). The following order was noted in increasing order (mean age in years): EM + CRPS (45), EM (46), Mig + CRPS (48), CM + CRPS (49), All (49.5), Mig (51), and CM (52). Migraine cohorts with CRPS (Mig + CRPS, EM + CRPS, CM + CRPS) were observably younger than their counterparts without CRPS (Mig − CRPS, EM − CRPS, CM − CRPS). Means, interquartile ranges, minimum, and maximum values are displayed by boxes and whiskers.
