Table combine both descriptive data on the total screened population (first column) and univariate participants characteristics comparison between each time the normal BP group versus elevated BP, versus poorly controlled BP and versus new discovered cases BP groups
aElevated blood pressure was defined as a systolic blood pressure (SBP) ≥ 140 mmHg and/or diastolic blood pressure (DBP) ≥ 90 mmHg
bComparison by unpaired t-test or χ2, Normal BP as comparison group of all p values
cElevated blood glucose ≥ 100 mg/dL after minimum 6-h fast
