Primary Outcome Measures

Name	Time	Method
degree of carotid artery stenosis on ultrasound - this measured during the ultrasound scan by measuring the velocity changes in the artery which correlate with the degree of narrowing. The faster the blood flow, the narrower the vessel.[150 case-control age and sex-matched pairs. The degree of narrowing is assessed at ultrasound, then the degree of narrowing will be compared statistically to the presence (or absence) of calcification on OPG at the completion of the trial]

Secondary Outcome Measures

Name	Time	Method
determine the sensitivity and specificity of carotid artery calcification on OPG. This is assessed by noting the presence or absence of calcification on each OPG reviewed, and by using ultrasound as the gold standard for detecting calcification.[end of trial - when all participants have had an ultrasound]
