Premarket evidence — what FDA accepted
source quote (p.5)
“DM-Density is a standalone software application that automatically analyzes "for presentation" full field digital mammograms to calculate breast tissue composition.”
source quote (p.5)
“The software processes full field digital mammograms according to proprietary algorithms and generates a Breast Density Grade in accordance with the American College of Radiology's Breast Imaging Reporting and Data System (BI-RADS) density classification scales.”

endpoints: Reliability was assessed using the Pearson's Correlation Coefficient by comparing the DM-Density percent density, dense breast area and total area measurements for Left and Right breasts as well as for CC and MLO views.; Accuracy was assessed by validating DM-Density percent density and total area measurements.; Accuracy was further assessed by validating the Breast Density Grade assessments to known Breast Density Grade assessments using the Kappa statistic.; Reproducibility was assessed with the Pearson Correlation Coefficient using a dataset from subjects who had two mammograms acquired on compatible mammography acquisition systems within a two year time period.; The inverse relationship between breast density and age was assessed by calculating the Pearson's Correlation Coefficient between DM-Density percent density measures and age at time of screening.

FDA source did not state a quantitative performance metric — non-reporting is itself the signal.
