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

Text: Due to ethical and legal restrictions, data are available upon request. Requests for data may be submitted to the Southern California Children Health Study (CHS). Investigators who want access to data will be required to submit a brief research protocol, which will be reviewed by the Childrenâs Health Study Health Data Release Committee and the USC IRB. Any data provided will be stripped of specific subject identifiers, including name, address, universal transverse mercator (UTM) coordinates, school locations, and any other data that could be used to identify a specific child or his/her residence. Recipients must agree to security policies, including password-protected access and encrypted storage that will minimize the risk of unauthorized distribution. The CHS also has a publications committee that reviews and approves all analyses and manuscript/publication proposals that use CHS data and reviews all finished products prior to publication. Readers who are interested in getting access to the data set used in this study could contact Dr. Frank Gilliland [Email: gillilan@usc.edu Phone: 323-442-1096] to reach the Childrenâs Health Study Health Data Release Committee.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
