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 cannot be shared publicly without a request for a data transfer agreement from the Tanzania national ethics committee. Individual requests for transfer of data can be directed to National Institute for Medical Research in Tanzania (contact via ethics@nimr.or.tz) for researchers who meet the criteria for access to confidential data. The data availability statement indicates that data is only made available by submitting requests for a data transfer agreement to the Tanzania national ethics committee (NIMR). As per NIMR requirements, data collected in Tanzania and that has been approved by NIMR can only be sent out of the country to a specified third party upon approval of a data transfer agreement for that institution. I have an approved data transfer agreement for data to be sent to the London School of Hygiene and Tropical Medicine, London UK. Data can be made available but require that individuals apply for DTAs allowing data to be sent to any other institution outside Tanzania.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
