Values are mean ± standard deviation or number (%)

P-values for continuous variables are from a two-sample t-test, from a normal approximation to the binomial for proportions and from a chi-square test for categories.

TIA indicates transient ischemic attack of eye or brain; BMI, body mass index; BP, blood pressure, GFR, glomerular filtration rate.

*History of previous or current hypertension

Treated for hypercholesterolaemia

Includes type I, type II and impaired fasting glycaemia
