You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: The data used in this work were obtained from the Prostate Cancer Association Group to Investigate Cancer Associated Alterations in the Genome (PRACTICAL) consortium, and from the ProtecT study. PRACTICAL consists of a collaborative group of researchers, each of whom retains ownership of their contributed data. Members of the consortium can use pooled data via proposals that are reviewed by the Data Access Committee. Approved proposals are then sent to the principal investigators of the PRACTICAL member studies, each of whom may opt to participate or not in the specific request. Readers interested in participating in the PRACTICAL consortium and gaining access to member data may find information about application at: http://practical.icr.ac.uk. ProtecT (http://www.bristol.ac.uk/population-health-sciences/projects/protect/) study data were provided by the principal investigators for the trials who retain ownership of this data; access to these data can be requested by contacting those principal investigators and submitting a request form for approval.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
