Figure 5.
PCA performed with the host parameters data set (n = 21). Individual samples are represented by points colored and linked according to the corresponding visit. The arrows depict the variables, here the host parameters. The longer they are, the more they drive the samples’ projections; the closer they are, the more they vary together. Specific parameter groups are highlighted in color (SCFAs, chemokines, and inflammatory parameters). For a better visualization, variables with negligible impact on sample projections (with small arrows) were removed from the figure after computation. CRP, C-reactive protein; IL, interleukin; IP, Interferon gamma-induced protein 10; MCP-1, monocyte chemoattractant protein 1; PC1, principal component 1; PCA, principal component analysis; TNF, tumor necrosis factor.
