Most significant deregulated miRNAs in breast tumors from relapsing patients.

#Group A  =  no recurrence, Group B  =  early recurrence (≤24 months after surgery), Group C  =  late recurrence (50–60 months after surgery).
*limma F, analysis of filtered data (sd>70%) using limma.
**RankProd, analysis of unfiltered data using RankProduct algorithm.
***RT-qPCR, Relative miRNA expression was calculated using the ΔΔCt method. The standard error (SE) was calculated based on the theory of error propagation [107].
