Gene pairs and triplets of genes with prognostic relevance for etanercept therapy in rheumatoid arthritis determined using support vector machines based on 46 selected probe sets of differentially regulated genes. Gene pairs with prediction accuracy Q > 89% and triplets of genes with prediction accuracy Q > 95% are shown. For gene function refer to Table 3.
