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: Due to ethical constraints, the data underlying this analysis cannot be made publicly available. The dataset cannot be completely de-identified without removing key variables such as country, cadre, facility level, facility sector, area type and all the open-ended questions. This de-identification would limit the value of the dataset, making any replication of the analysis impossible. Data requests can be sent to the study PI Prof Lenka Benova at lbenova@itg.be and the ethics committee at the Institute of Tropical Medicine at irb@itg.be.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
