Figure 1.
Overview of the microarray data. A–C, First 3 components (PC1–3) from principal component analysis of the gene expression profile are plotted. Ellipses represent 0.7 standard deviation from the mean value for the indicated categories (patient and control). D, The molecular distance to health (MDTH) for each sample is shown. E, Samples are categorized by week. The distribution of MDTH for each category is shown as a box plot. ** indicates a significant difference (P value < 2 × 10−5, Wilcoxon rank sum test) compared to the control.
