According to Bonferroni’s correction, a fitness p-value <6.944×10 9 and a randomization test p-value <0.00208 were considered significant. The p-values of the models showing significant association with rheumatoid arthritis comparing RA vs. CTR are in bold. Of these 12 pathways, five were replicated in NARAC dataset at the significance level of 0.00208 and three were replicated at the significance level of 0.05. The p-values of these replicated models are also in bold.
