Studies with fewer than 20 BC instances had been excluded. Although these signatures mostly reflect higher amounts of circulating miRNAs, some miRNAs are detected at lower levels in blood samples of BC sufferers. Blood collection was performed prior to surgery unless otherwise indicated. miRNAs shown in bold indicate a recurrent presence in a minimum of 3 independent studies.
