Circ‐LARP4 expression in tumor and non‐tumor tissue from osteosarcoma patients. The expression of circ‐LARP4 in tumor and non‐tumor tissue (A) and the ROC curve analysis of circ‐LARP4 expression for differentiating tumor tissue from non‐tumor tissue (B). Comparison was determined by Wilcoxon signed‐rank test. ROC curve was used for assessing the value of circ‐LARP4 expression for differentiating tumor tissue from non‐tumor tissue. P value <.05 was considered statistically significant. Circ‐LARP4, circular RNA La‐related RNA‐binding protein 4; ROC, receiver operative characteristics; AUC, area under curve
