Figure 3.

Off-domain Evaluation of Performance—Averaged Over All Imaging Findings. The results are represented as AUROC values averaged over all labeled imaging findings. The dataset outlined above each subpanel provides the test set, while the first four columns (orange) indicate the AUROC values when trained locally on other datasets, i.e., off-domain. The fifth column (light blue) indicates the corresponding AUROC values when trained off-domain yet collaboratively while including all four datasets (federated learning). Otherwise, the figure is organized as Fig. 2. Mind the different y-axis scales.
