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: data are from the awhs study whose steering committee may be contacted through the corresponding author. data can be made available to all interested researchers upon request. the epidemiological study that provides the framework for this analysis is a publicly funded study which collects and holds the data. epidemiological studies make use of thousands of data points that may pose a threat in confidentiallity if released freely. the informed consent that the participants signed authorised the study researchers to hold the data and to use it to produce scientific results, but limits third party access to signed agreements. in addition, given the investment of the institutions in data collectection they request to control access to it to third parties. data used for a particular analysis may yield results for many different analyses, as hundreds of variables that are used for adjustments in one study may be the the main target of analysis in another. this is another reason why these data can only be accessed per request. in this regard, the steering committee of the study will analize the proposals (the request will be forwarded through the corresponding author). after approval, a data sharing agreement must be signed between the institution of the proposers and the study institutions (spanish national center for cardiovascular research and instituto aragones de ciencias de la salud). this mechanism would also be available for researchers willing to audit the analysis.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
