Study of the Effect of Breast Tissue Density on Detection of Masses in Mammograms

Table 3

This table shows the average results obtained over the different test subsets (considering all the prototypes, or only for those with a given density), as area under the ROC curve (AUC) for a confidence interval (CI) of 95%.
