Fig. 1From: Serum microRNA array analysis identifies miR-140-3p, miR-33b-3p and miR-671-3p as potential osteoarthritis biomarkers involved in metabolic processes a Graphical representation of the downregulated differentially expressed (DE) miRNAs between OA patients and healthy individuals. Fold change has been estimated by calculating the log 2 of the OA over control ratio. b Graphical representation of the upregulated differentially expressed (DE) miRNAs between OA patients and healthy individuals. Fold change has been estimated by calculating the log 2 of the OA over control ratioBack to article page
