Fig. 4From: Identification of differential co-expressed gene networks in early rheumatoid arthritis achieving sustained drug-free remission after treatment with a tocilizumab-based or methotrexate-based strategyNetwork visualization of the interaction of gene co-expression within the tocilizumab plus methotrexate (a, salmon module), tocilizumab (b, purple module), and methotrexate (c, black module). Upregulated genes are expressed in green nodes and downregulated genes in red nodes. The rounded rectangular nodes display the highest co-expressed genes within the module (signature genes)Back to article page
