Point estimates (and 95% confidence intervals shown in parentheses) represent mean differences in diastolic blood pressure (mmHg) between comparison and referent groups. Age adjustment refers to adjustment for baseline age and time from baseline age. Modeling for baseline age and time from baseline was as follows: age+age2+time+ time2+age*time+age*time2+age2*time+age2*time2.

Conventional risk factors include antihypertensive medication, smoking, body mass index and alcohol consumption.
