Fecal microbes, short chain fatty acids, and colorectal cancer across racial/ethnic groups

Figure 1 Levels of individual and total short chain fatty acids by race/ethnicity. All values are in mg/mL of stool. A: The levels of short chain fatty acids (SCFAs) in stool across all four racial/ethnic groups; B: The levels of SCFAs for African Americans vs those of all other races/ethnicities. ¹Statistically significant difference by independent samples t test, two sided, equal variances not assumed. Acetate: P = 0.045; Butyrate: P = 0.043; Total SCFAs: P = 0.039.
