Predicted vs. Actual Hb variations for a patient characterized by a prediction error close to the mean absolute error on test set.

<p>At each time step (corresponding to monthly lab tests, on the x-axis), the Hb variation predicted by the model over the next three months (i.e., Hb(t+3)–Hb(t), on the y-axis) is plotted in solid line and compared with the actual variation observed over the same time interval (plotted in dashed line). Time steps are counted starting from the first month for which an Hb prediction for the patient was possible.
