FENDRR and osteosarcoma: To further assess the relationship between lincFOXF1 expression and osteosarcoma clinicopathological features, osteosarcoma patients were separated into high‐ and low‐lincFOXF1 groups according to median values, and we found that lower lincFOXF1 expression was significantly correlated with Enneking stage (P = 0.042) and metastasis (P = 0.008) (Table 1).
