The diagnostic value of PPARγ protein expression level to differentiate between benign and malignant tumors (Cut off value < 10.06, AUC = 0.91, P < 0.0001), between benign and control groups (Cut off value < 7.41, AUC = 0.81, P < 0.0001), between malignant and control groups (Cut off value < 10.06, AUC = 0.96, P < 0.0001) and between total bone tumors and normal bone tissues (Cut off value < 7.41, AUC = 0.91, P < 0.0001). Here, PPARG is linked to cancer.
