Fig. 3. Enterotype-like clustering analysis in the fecal samples of male and female rats fed control (CON) or high-fat diet (HFD). There are two fecal enterotypes (E1 and E2) in males (A) and three enterotypes (E1, E2, E3) in female rats (B). The optimal cluster number was determined by maximizing the Calinski-Harabasz index value (Figure S2).
