“…Of the studies that 3examined the effect of DM in breast screening programs (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27), five compared DM with SFM in concurrent cohorts (20,21,23,25,27), using mainly DR technology. Most found similar cancer detection rates (20,21,23) and positive predictive values (20,21,25) but also reported significantly higher recall rates for DM than for SFM (20,25).…”
