Studies with fewer than 20 BC cases were excluded. Though these signatures mainly reflect higher amounts of circulating miRNAs, some miRNAs are detected at reduced levels in blood samples of BC patients. Blood collection was performed before surgery unless otherwise indicated. miRNAs shown in bold indicate a recurrent presence in a minimum of three independent studies.
