PRR13 and breast cancer: The univariate analysis model revealed that clinical stage (HR = 0.595, p = 0.039), ER expression (HR = 2.192, p = 0.008), PR expression (HR = 2.137, p = 0.011), and PRR13 expression (HR = 0.449, p = 0.008) showed prognostic implication for the predication of breast cancer.
