Figure 3

Each symbol represents a sample. (A) Microflora of the jejunum. The first two PCA scores were 62.25% and 20.42%, accounting for a total variation of 82.67% between the IAH and control group. (B) Microflora of the colon. The first two PCA scores were 45.77% and 27.01%, accounting for a total variation of 72.78% between IAH and control groups. (C) Microflora of the jejunum and colon. The combined data from the colon and the jejunum. The symbols identify four groups that can be separated.
