* Arsenic Concentration.: Drinking water arsenic concentration in microgram/liter; § Systolic hypertension: Systolic blood pressure ≥140 mmHg; ψ Diastolic hypertension: Diastolic blood pressure ≥90 mmHg, φ Pulse pressure: categorized as <55 mmHg and ≥55 mmHg; 95% CI: 95% Confidence interval. † Reference category. Adjusted for age, sex, education, marital status, religion, monthly income and BMI. ** Crude Odds Ratios: For overall hypertension 0.60 (CI: 0.35–1.01), systolic hypertension 0.72 (CI: 0.45–1.15), diastolic hypertension 0.89 (CI: 0.60–1.31) and for increased pulse pressure 2.06 (CI: 1.07–3.93).
