Principal component analysis of the gut microbial relative abundance data reveals tighter clustering of samples with prolonged exposure to high-fat high-sucrose diet.
Results are plotted according to the first two principle components, which explain 50.6% (PC1) and 19.2% (PC2) of the variation in gut microbial composition between samples. The clustering of samples within each group is represented by their respective 95% confidence interval ellipse.
