Text: requests for data may be sent to dr. judith a. cook, the corresponding author for this manuscript. data come from four community mental health centers whose identity and location are identified. the data set includes self-reported demographic and behavioral data from interviews, results of medical tests, and findings of health risk assessments. sensitive information includes: 1) illegal substance use; 2) substance use disorders; 3) mental health disorders; and 4) hiv status. even though the data set has been stripped of identifiers, we believe that there remains the possibility of deductive disclosure of subjects with unusual characteristics. thus, we will make the data and associated documentation available to users only under a data-sharing agreement executed with the university of illinois at chicago.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
