To explore the relationship between osteosarcoma metastasis and RP11-472M19.2. ROC curves for predicting osteosarcoma metastasis in the whole cohort of FAM222A-AS1, RP5-1011O1.2, RP11-274H2.2, RP11-654A16.3. RP11-472M19.2 was used in the whole cohort (E) and training group (G) for diagnosing osteosarcoma metastasis. (F) Box plot showing significantly higher expression of RP11-472M19.2 in the metastasis group. (H) Dot plot of the correlation between osteosarcoma metastasis-associated gene MET, FASN, HES4, EZH2, DNMT3A, HEY1, FAS, DCN expression and the expression of RP11-472M19.2.
