BCR and posterior cortical atrophy: Further Cox proportional hazards multivariate model revealed that the prediction efficiency of miR-30d/MYPT1 combination to BCR of PCa patients was stronger than the two markers’ alone (For prognostic implication of MYPT1 based on its immunostainings using human PCa tissue microarrays: Table 1; For prognostic implications of miR-30d and/or MYPT1 based on the Taylor dataset: Additional file 3: Table S9, P value of miR-30d/MYPT1 combination for BCR-free survival vs. P values of miR-30d or MYPT1: 0.026 vs. 0.027 or 0.624).
