  1. an = 457 participants and n = 1260 non-respondents. bn = 796 participants and n = 2686 non-respondents. In some cases (n=7) the maximum reported SBP and DBP were not biologically plausible values, thus maximum SBP was restricted to between 60-270 mmHg and maximum DBP was restricted to 40-180 mmHg
