Prospective model performance

Model	Cohort	Se	Sp	PPV
Any AKI	Training	0.610	0.775	0.790
	Testing	0.605	0.776	0.791
	Validation	0.619	0.777	0.796
Moderate/severe AKI	Training	0.689	0.734	0.543
	Testing	0.687	0.733	0.544
	Validation	0.694	0.739	0.546

The model performance when evaluated prospectively. Encounters are counted as 'positive' if the model triggers in a 'timely' manner before onset (see Methods) and negative if not. Results for each model are shown for the training, testing, and validation sets. Se=sensitivity; Sp=specificity; PPV=positive predictive value.
