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

Text: the original data was not collected by the authors, but made available by record-linkage, using the danish unique individual civil registration number (cpr) by the following parties: the danish civil registration system (cvr), maintained by the state serum institute (ssi); and the danish childhood diabetes registry (dsbd). the final dataset with the record-linkage was created by a statistician at the institute of preventive medicine, frederiksberg hospital (ipm). according to a permission received from the danish data protection agency (ddpa), the principal investigator (blh) is not allowed to forward the record-linkage dataset with information on individuals, made anonymous by ipm, to other researchers outside ipm. any researcher with approval from ddpa is able to create an almost identical dataset by contacting ssi research service (contact information: forskerservice@ssi.dk) and the steering committee of dsbd (contact person: jannet svensson jannet.svensson@regionh.dk). the principal investigator will provide metadata (tables) on request to other researchers, for example showing results of alternative analytic strategies.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
