Data Collected

The CSHA collected data using interviews and questionnaires; it undertook clinical, neurological and neuropsychological examinations, and made physical measurements of mobility and blood pressure. In addition, laboratory tests were undertaken, and blood samples were collected for genetic and other analyses. Finally, we abstracted information from death certificates and provincial health care utilization records for the study period.

The table provides an overview of the data collected, and indicates the numbers of cases and of variables in the various data sets to show the magnitude of the study.
