(a) Log Fold Change (LogFC) calculated as Chronic migraine / Healthy Controls. Positive logFC indicates bacteria that were significantly more abundant in chronic migraine group and negative logFC indicates bacteria that were significantly more abundant in healthy controls. (b) LogFC of significantly different bacteria between subjects with and without IBS. Positive logFC indicates bacteria that were significantly more abundant in subjects with IBS and negative logFC indicates bacteria that were significantly more abundant in subjects without IBS. (c) LogFC of significantly different bacteria between subjects with a chewing time of less or more than 20 s for each bite. Positive logFC indicates bacteria that were more abundant in subjects with a chewing time of more than 20 s and negative logFC indicates bacteria that were more abundant in subjects with a chewing time of less than 20 s. The fold change of all bacteria that showed significant differences between the two groups in statistical tests with a p-value less than 0.05 is shown in this figure
