| Treatment protocol |
Participants were enrolled on an ongoing basis in a lifestyle intervention that consisted of four components: 1) a very low fat vegetarian diet (<10% of calories from fat); 2) 180 minutes/week of moderate aerobic exercise; 3) one hour of stress management each day; and 4) weekly group support sessions (40). Clinical staff met with patients twice each week during the first 12 weeks to orient participants to the program and maximize adherence. The remainder of the program was primarily self-directed but included ongoing weekly stress management and group support sessions.

| Description |
Gene Expression Data from a matched Control Group participant
|
| Data processing |
Partek® Genomics Suite v6.5 (Partek Incorporated) was used to analyze gene expression data from the 378 CEL files, which all passed standard QC assessment. Duplicate blood samples collected at each time point from 7 random participants indicated high repeatability of the microarray data (average Pearson correlation of normalized intensities was 0.992 + 0.006, range 0.969-0.996). Paired t-tests identified 9 genes that were excluded from further analysis because they showed significant differences in expression among duplicate samples based on a false discovery rate (FDR) adjusted P-value <0.05
