3.4.5 - Ethnicity
Only two studies looked at different ethnic populations separately within their study. One(6) found that DELC was more prevalent in caucasian than non-caucasian populations but there was still a significant association with CAD in both groups. Another(12) attempted to investigate this as well but cases and controls were not well matched on gender and race and no meaningful results were obtainable. Overall the twelve studies covered multiple ethnic populations from around the globe and it is believed that this suggests the findings are applicable to a wider population although variations between ethnic groups can not be excluded.
