Figure 3.

Kaplan-Meier curves of the four miRNAs showing strongest association with distant-metastases free survival (DMFS) in triple-negative tumours. Patients are stratified into three groups according to the miRNA expression level tertiles. (a) "favourable" miRNAs, whose expression is associated with better prognosis (HR < 1) (b) "unfavourable" miRNAs, whose expression is associated with poorer prognosis (HR < 1). The hazard ratio indicates the risk change if miRNA expression rises by one standard deviation.
