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

Text: data are accessible in principle by applying for access directly from each contributing cohort. the iedea-sa dataset is a multi-site collaboration and this analysis combined data from different sites. (for more information, see http://www.iedea-sa.org.) the data do not belong to iedea-sa; data ownership remains with the participating sites. each site has approval from its own local institutional review board to collect routine data on patients and to transfer these data anonymously to the iedea-sa data centre, for use in collaborative analyses. interested readers may contact the site investigators to request the data, and this can be facilitated by the iedea-sa project manager, dr. morna cornell (morna.cornell@uct.ac.za).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
