For days with migraine in the past 4 weeks, the difference in the change from baseline between the sham diet and the true diet groups was significantly attenuated after adjusting IL-6 and TNF-α (i.e., p-value = 0.0098 for the unadjusted model vs. p-value = 0.0757 for the adjusted model). This evidence concerns the gene IL6 and migraine disorder.
