Density prediction performance in comparison to previous work

Model	4-Class Accuracy (95% CI)	AUROC (95% CI)
Wu et al.14	76.7% (??.?–??.?)	91.6% (??.?–?.??)
Lehman et al.16	77.?% (76.?–78.?)	??.?% (??.?–?.??)
Matthews et al.17	82.2% (81.6–82.9)	95.2% (95.0–95.4)
Magni et al.18	78.2% (??.?–??.?)	??.?% (??.?–?.??)
Our model (FFDM/2DS)	82.4% (81.5–83.4)	96.0% (95.7–96.3)

Performance comparison is indicative only as each evaluation was done on different test sets. The ‘?’ indicates unknown values that were not reported in the literature.

FFDM full-field digital mammography, 2DS two-dimensional synthetic.
