ONDRI’s Research Data
ONDRI’s data meets the highest quality standards
ONDRI adopts the highest standards when it comes to its research study data. The goal is to provide accurate, replicable data that promote data sharing, validation and collaboration among scientists and research groups.
High data quality is at the centre of honouring the commitment of ONDRI’s study participants: people living with the diseases studied, including care partners.
Brain-CODE: Platform for data cross-analysis
Data from ONDRI studies are stored in Brain-CODE. Brain-CODE is the Ontario Brain Institute (OBI’s) state-of-the-art neuroinformatics platform where data collected from their six research programs are stored and analyzed. OBI’s Brain-CODE is a “shared brain” for researchers in Ontario and beyond.

Data from ONDRI’s Foundational study (2013-18)
The Foundational study involved collecting detailed assessment data for each study participant, over a three year period (starting at baseline). All participants had a minimum of two years of longitudinal data collected.
The same study protocol was followed for participants in each disease group, in order to collect comparable data. This effort yielded millions of data points.
14 clinic sites recruited participants for ONDRI’s foundational study. Clinicians and research staff worked with study participants to help assess their disease progression, activities and other life factors utilizing standardized tests, questionnaires and other tools. Intensive quality assurance and quality control standards and training were provided for research staff collecting, recording and uploading the study data.

Novel process of standardization
Each lab in ONDRI’s Foundational study produced data in technology-specific formats (e.g. different branded MRI machine formats). To address this variation and enable effective cross-platform, cross-disease analysis following data collection, ONDRI researchers used specialized standardization tools and techniques. ONDRI datasets have thus been standardized, curated and cleaned using a highly interactive and thorough set of processes. This should provide researchers accessing these data a high level of comfort with regard to data replicability and quality.

ONDRI’s place in research on neurodegeneration and dementia
ONDRI’s unique Foundational study has generated one of the best characterized, cross-disease, cross-platform, multi-visit datasets worldwide. Baseline data are being released to the worldwide scientific community first, followed by longitudinal study data. Data from other ONDRI studies are scheduled to be released at a later date.
Sharing ONDRI’s extensive datasets allows researchers and collaborators outside of ONDRI to draw conclusions with confidence in their search for better diagnosis and treatment methods for neurodegenerative diseases, stroke and dementia.
ONDRI is One of OBI’s Six Integrated Discovery Programs
ONDRI is an Integrated Discovery Program within the Ontario Brain Institute (OBI) framework.
Leveraging Ontario’s publicly funded healthcare, world-class brain scientists, clinicians and brain institutions, ONDRI has a unique opportunity to contribute to the global effort to understand brain health disease.
