NR4A1 and neoplasm: Univariate analysis revealed that the critical covariables influencing prognosis (P ≤ 0.20, as determined by the Mantel-Cox log rank method) were the tumor histology (P = 0.004), size of the primary tumor (P = 0.057), distant metastasis (P = 0.022), grade of malignancy (P = 0.005), hormone receptor status (P = 0.003) and interval between first symptoms and diagnosing of cancer (P = 0.009).
