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 authors confirm that, for approved reasons, some access restrictions apply to the data underlying the findings. data are available on request from the national cancer registry (ncr) of ireland (contact person: dr sandra deady, data analysis group). it is the policy of the ncr that datasets which are anonymised but which, nevertheless, include sufficient detail or combinations of variables that potentially there may be a risk of compromising patient confidentiality are classed as restricted. requests for such data from the ncr must be approved on a case-by-case basis, by the registry director or deputised staff, and such datasets cannot be provided to research repositories outside of the ncr. further details of the ncrs data confidentiality policy, and procedures for requesting data, are available at: http://www.ncri.ie/sites/ncri/files/documents/ncri-data-confidentiality.pdf. datasets provided to bona fide external researchers will always exclude directly identifiable fields, but some further anonymisation of fields (e.g. dates of diagnosis) may also be required to minimise the risk of inadvertent disclosure of patients identities.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
