Figure 2.

Graphs comparing temporal trends of prediction error for all days and unstable days across development, temporal, and prospective validation cohorts.

Temporal trends of prediction error for all days and unstable days. Reference SCr was defined as the measured SCr on the day of making the prediction. Predicted SCr was defined as the predicted SCr by Nephrocast on the next patient-day. Measured SCr was defined as the laboratory measured SCr on the next patient-day. Model error was defined as the difference between measured SCr and predicted SCr, which was compared against the difference between measured SCr and reference SCr. Unstable days were defined as those in which there was a change of 30% or 0.3 mg/dL or more in SCr concentration between the reference SCr and the measured SCr on the following patient day. Abbreviation: SCr = serum creatinine.
