  1. Results of ingenuity canonical pathways analyses, with pathways reaching significance at p > 0.05 included. Ratio refers to the number of differentially expressed skeletal muscle genes significantly associated (Spearman correlations, p < 0.05) with improvements in rheumatoid arthritis (RA) (RA) (n = 12 participants) disease activity score in 28 joints (DAS-28) following high-intensity interval training (HIIT) compared to the total number genes in that pathway. Subsequent significant pathways with at least 50% gene overlap from previous listed pathways are filtered from this table. Please see Supplementary Table 4 for full list of significant canonical pathways
