Fig. 2From: Preliminary evaluation of the publicly available Laboratory for Breast Radiodensity Assessment (LIBRA) software tool: comparison of fully automated area and volumetric density measures in a case–control study with digital mammographyRelationship between different breast density measures. The association between the area-based and volumetric breast density is provided for both (a) absolute measures and (b) percent measures. The relationship between absolute and percent breast density measures are shown for (c) volumetric and (d) area density. Cancer cases are demarcated by ‘x’, controls by ‘o’. Regression lines, equations, and Spearman correlations are provided for referenceBack to article page
