A log-rank analysis indicated that high miR-520h expression in the tumor tissues predicted poor survival in breast cancer patients (P = 0.011, Figure 5(a)), whereas patients with high expression levels of OTUD3 (P = 0.010, Figure 5(b)) and PTEN (P = 0.029, Figure 5(c)) had better survival rates than those with low expression levels. Here, PTEN is linked to neoplasm.
