Table 2 Shows both groups’ migraine days/month, intensity, HIT-6, and MIDAS at the baseline and after three months of each diet; results for chronic and high-frequency episodic migraineurs are also presented. There was a significant reduction in all variables studied. A paired t-test or a Wilcoxon test was used to compare; significance was determined with a p-value of 0.05
