The OHTN Cohort Study
The OHTN Cohort Study (OCS) is a community-governed, scientifically rigorous research initiative, designed to improve the health and well-being of people living with HIV in Ontario by promoting and supporting scientific, community-based and policy-relevant research. The OCS is a multi-site research study that collects clinical and sociobehavioural data on a cohort of participants living with HIV over time. The mission of the OCS is to develop, support and sustain a unique research database and cohort, governed by people living with HIV in Ontario and used in partnership by scientists, community-based researchers and other stakeholders.
