  1. Values are mean±s.d. or number of subjects (%). An ellipsis indicates information that was not collected. Hypertension was an office blood pressure of at least 140 mm Hg systolic or 90 mm Hg diastolic or use of antihypertensive drugs. Significance of the sex difference *P<0.05, P<0.01 and P<0.001.
