Race prediction performance across different models

Model	Accuracy (95% CI)	AUROC (95% CI)
Race prediction model	86.7% (86.0–87.4)	95.1% (94.7–95.5)
Fine-tuned Model A	74.2% (73.3–75.3)	80.8% (80.0–81.9)
Fine-tuned Model B	75.8% (74.8–76.8)	82.8% (81.9–83.6)
Fine-tuned Model C	73.2% (72.2–74.3)	79.2% (78.4–80.3)

First row shows the performance of a model trained specifically for race prediction. Rows two to four show the performance for race prediction of models that were built by fine-tuning the model backbones of breast density prediction models. Density models A and B were originally trained for density prediction using data from a single race group only.
