2 List of Supplementary Data Files Supplementary Data file 1. Fold-changes and ANOVA p-values for the lipids in liver and plasma samples. The columns S/N, H/N, C/N and H/S list the fold-change. The column "Pvalue(N,S,H,C)" lists the ANOVA p-value across the four classes. Supplementary Data file 2. Fold-changes for genes related to different lipid categories. Supplementary Data file 3. Cross-correlation between lipids and matrix metalloproteinase (MMP) and related (TIMP) genes. Supplementary Data file 4. Result of pair-wise SNP analysis among the four classes, N, S, H and C, using plink, for PNPLA3 SNPs. For example, the sheet plink_ns_snp_pnpla3 shows the results for comparison between the N and S samples. Supplementary Data file 5. (A) Result of procedure LDA2 on plasma lipids to classify NASH vs. steatosis samples. First, LDA was applied on 30 top ANOVA lipids, then on 20 selected lipids (see also Supplementary Fig. S7). LDA coefficients and mean values for the two classes, steatosis (S) and NASH (H), for the 20 lipids are listed. (B) Prediction of the class, steatosis (S) or NASH (H), during k-fold cross-validation. The columns H and S list the predicted probability for the respective class.
