Figure 1. Bar graph shows significantly lower underestimation rates for biopsies performed with a vacuum-assisted device, as compared with those performed with a large-core device in lesions with a maximum diameter of 1-10-mm (P < .004) or 11-20 mm (P < .006) but not for lesions with a maximum diameter of 21 mm or greater (P > .5).
