Notes: Only data from individuals who completed the modules marked with * were considered as participants with completed cardiovascular data (total 989/994). It is expected that missing data will exists in certain specific questions, measurements or laboratory tests for various reasons, but this did not disqualify the individual's information to be used on the data analysis process.
