Relationship between AURKA levels in breast carcinomas and metastasis-free survival (MFS). A. Patients were subdivided into four percentiles with increasing AURKA expression and analyzed by Kaplan-Meier plots. Red, green, dark blue, light blue represent the 1st, 2nd, 3rd and 4th quartiles of AURKA expression, respectively. B. Similarly, six groups of equal case numbers were analyzed. The colors red, green, dark blue, light blue and yellow show groups of patients with increasing AURKA expression.
