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 irb-approved reasons, access restrictions apply to the data underlying the findings. for this study, consent was not obtained for the sharing of data outside of the research team. it is therefore not possible to make the data publicly available, even in a pseudo-anonymized (coded anonymized) form. the dataset is relatively small, and the basic demographic variables (age and gender), which would need to be shared in order to allow other researchers to duplicate the analysis, are sufficient to identify individual patients even after anonymization. the details in the methods section of the manuscript are adequate to allow others to replicate the study in a similar population and state. if researchers are interested in accessing the data, they can apply to the kek zurich, and their application will be assessed on a case by case basis, possibly requiring additional ethics approval and/or informed consent from the participants.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
