From: Characterizing advanced Parkinson’s disease: OBSERVE-PD observational study results of 2615 patients
Clinical PD assessments based on DAT eligibility and status. Comparisons between DAT groups (ongoing, planned, not planned, and ineligible) are shown for (a) activities of daily living (UPDRS II) and motor symptom severity (UPDRS III), b dyskinesia duration and disability (UPDRS Part IV Q32 and Q33), c average duration of “Off” time (UPDRS Part IV Q39), and (d) NMS burden and QoL (PDQ-8). Error bars indicate the standard deviation. p values from a paired t test indicate statistical significance. An asterisk indicates significant differences between DAT-ineligible patients and all DAT-eligible patients combined. DAT = Device-aided treatment; NMSS = Non-motor Symptom Scale; NS = Not significant; PDQ-8 = Parkinson’s disease 8-item questionnaire; SD = Standard deviation; UPDRS = Unified Parkinson’s Disease Rating Scale
