Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.

PSS000088 Parkinson Disease symptom progression was assessed during 1 to 3 follow-up examinations by a movement disorder team (June 1, 2007, to August 31, 2013; mean [SD] time from disease onset, 7.3 [2.8] years) using the following methods: - Cognitive decline was determined with the Mini-Mental State Examination (MMSE; range, 0-30, with lower scores indicating worse cognitive function). Cognitive decline was defined as a 4-point decrease from baseline MMSE score and time to event as the time from the baseline to follow-up examinations in which a 4-point decrease was first measured - Motor decline was defined as a 20-point increase in Unified Parkinson’s Disease Rating Scale part III (UPDRS-III) score, and time to event as the time from the baseline to follow-up examinations in which a 20-point increase was first measured. - Motor decline was also measured by assessing conversion to stage 3 or higher of the Hoehn & Yahr (H&Y) scale. Time to conversion to H&Y stage 3 was defined as the time from the baseline to first follow-up examinations in which the patient scored at least stage 3. Mean = 5.3 years

European PEG Patients with idiopathic PD diagnosed less than 3 years previously were recruited from June 1, 2001, through November 31, 2007. Patients were confirmed as having clinically probable or possible Parkinson Disease by a team of movement disorder specialists
