Validation of differentially expressed miRNAs in older (N = 10) versus young (N = 20) breast cancer patients and comparison between older ‘fit’ (N = 10) and older ‘frail’ (N = 10) subjects.

aP-values are derived from parametric t-test (unpaired, 2-tail, C.I = 95%), unless data are not normally distributed (values indicated in italic). In such cases, P-value derived from Mann-Whitney test is displayed. Bold values indicate significant values according to the 5% significance threshold. Values indicated with an asterisk (*) remained significant after correction for multiple testing.bNegative values indicate x-fold decreased expression, positive values indicate x-fold increased expression.Validation of differentially expressed miRNAs in older (N = 10) versus young (N = 20) breast cancer patients and comparison between older ‘fit’ (N = 10) and older ‘frail’ (N = 10) subjects.
