Fig. 2From: 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 strategyHierarchical cluster dendrograms of the differently expressed genes included in the network analysis within the (a) tocilizumab plus methotrexate, (b) tocilizumab, and (c) methotrexate strategy arms. Each line represents an individual gene and the branches correspond to modules of co-expressed genes, which are labelled by coloursBack to article page
