Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Data cannot be shared publicly because of ethical considerations particularly the potential of participant identity disclosure. Data are available from the Manhi√ßa Health Research Centre (CISM), based on the Institutional Data Access Policy. Researchers whose objectives meet the criteria for confidential data access may contact francisco.saute@manhica.net (President of the CISM Scientific Committee) or sozinho.acacio@manhica.net (President of CISM IRB). Data request shall consist of a formal letter addressed to the institution's Scientific Director. Should the response be favourable, researchers can then submit an analytical and publication plan to the Internal Scientific Committee. Should there be clearance, data transfer shall proceed under a Data Transfer Agreement (DTA) between the institution requesting permission for data access and the CISM. Selection of specific data to be shared and removal of potentially identifiable information will be performed prior to data sharing.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
