Correlation analysis reveals some significant associations regarding the type of migraine (without migraine, migraine with or without aura) of the studied cytokines, respectively, IL-8 (rS = 0.38, p = 0.0036), PAI-1 (rS = −0.43, p = 0.0018), and sICAM-1 (rS = −0.37, p = 0.0072), show one positive and two negative associations (Figure 1A). The gene discussed is CXCL8; the disease is migraine disorder.
