Figure 4. Fecal levels of short-chain fatty acids (SCFAs) and medium-chain fatty acids (MCFAs).

Figure 4

(A) The levels of SCFAs (Acetate, Butyrate, Iso-Butyrate, Propionate, Valerate, Iso-Valerate) and MCFAs (Hexanoate and Heptanoate) were quantified in fecal samples of all groups. While no difference were found in any of the SCFAs, both MCFAs levels were significantly lower in PsA and Ps samples, compared to healthy controls (P<0.01 and P<0.05, respectively). (B) Total levels of fatty acids (CFAs) were similar among groups.
