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

Text: participants were assured their information would remain anonymous. names of patients, family members, healthcare professionals and certain locations were removed from the transcripts by the transcription service. however, patients could still potentially be identified through details in several of the transcripts either because their cancers were relatively rare, their diagnostic pathway was unusual. removing that detail would render the transcripts incoherent, but making publicly available would conflict with the agreement with participants to keep the information they share anonymous. therefore, data are not made publicly available. these data will be available upon request, by contacting the paper's lead author: g.black@ucl.ac.uk.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
