Patient disposition. This figure shows the disposition of patients who responded to the survey. The patient dataset comprises all patients who met the inclusion and exclusion criteria. Patients who met ≥1 of the 5-2-1 diagnostic criteria (≥5 oral levodopa doses a day, ≥2 hours of off time a day, troublesome dyskinesia ≥1 hour a day) were classified as having APD. Patients who did not meet any of the 5-2-1 diagnostic criteria were classified as having non-APD. Patients who could not be classified as having APD or non-APD because of missing or unknown data were classified as unknown. APD, advanced Parkinson's disease; PD, Parkinson's disease.
