Results of the comparison between local and FFL-based training of VinDr-CXR dataset with overlapping labels for different training set sizes, tested on the VinDr-CXR benchmark.

	Local VinDr 2K	FFL VinDr 2K	Local VinDr 5K	FFL VinDr 5K	Local VinDr 15K	FFL VinDr 15K
AUROC	0.77 ± 0.08	0.78 ± 0.06	0.79 ± 0.07	0.82 ± 0.05	0.83 ± 0.09	0.84 ± 0.05

Average AUROC values over no finding, aortic enlargement, pleural thickening, cardiomegaly, pleural effusion, pneumothorax, and atelectasis. The FFL was performed in combination with UKA-CXR dataset of n = 122,294 images with 7 other labels including cardiomegaly, pleural effusion right, pleural effusion left, pneumonic infiltrates right, pneumonic infiltrates left, atelectasis right, and atelectasis left.
