Ablation study using a subset of the training data.

Training dataset size	AUROC	Sensitivity	Specificity	PPV
25%	86.325 (± 2.9)	9.663 (± 5.6)	99.616 (± 0.3)	63.483 (± 26.8)
50%	87.965 (± 3.3)	14.962 (± 5.6)	99.374 (± 0.4)	62.781 (± 14.4)
75%	88.365 (± 3.3)	17.015 (± 5.7)	99.315 (± 0.4)	62.221 (± 13.262)
100%	88.761 (± 3.0)	18.514 (± 5.5)	99.266 (± 0.4)	63.431 (± 12.7)

In each row, we report the AUROC, sensitivity, specificity, and positive predictive value (PPV) for the EPPT trained using a random subset of the training data. Each value denotes the mean (in percent) computed across 20 cross-validation folds and in parentheses we show the standard deviation.
