Fig. 2From: Osteopontin‐induced lncRNA HOTAIR expression is involved in osteoarthritis by regulating cell proliferationHOTAIR and osteopontin were positively correlated across OA patients. Correlations between HOTAIR and osteopontin mRNA across synovial fluid samples from both OA patients (a) and healthy controls (b) were analyzed by performing linear regression analysisBack to article page
