Figure 3From: Associations between cerebral and systemic endothelial function in migraine patients: a post-hoc study Correlation between CVR to L-arginine in the MCA and the PCA. Correlation between cerebrovascular reactivity (CVR) to L-arginine in the middle cerebral artery (MCA) and the posterior cerebral artery (PCA) in all migraine patients (p < 0.001; r2 = 0.377) and healthy subjects (p = 0.001; r2 = 0.481).Back to article page
