Fig. 7From: Whole blood microRNAs as potential biomarkers in post-operative early breast cancer patientsProgression-free survival (PFS) according to whole blood miR19a levels. High (H) and low (L) miR19a levels were defined as being above or below the mean values of miR-19a in HDs plus 1standard deviation (SD). PFS was analyzed using the Kaplan-Meier method and survival estimates in different groups were compared using the log-rank testBack to article page
