The coordinates of the dots are determined by the value the model predicted for a given patient in a given questionnaire vs. the actual value the patient obtained. Please note that for the IPSS, lower MAEs are expected due to the scale only ranging from 0–35 compared to the EPIC, which ranges from 0–100. MAE = Mean Absolute ErrorBack to article page
