Dependent variable: The hypertension prevalence was divided into quintiles. (i.e., the respondents were split into five groups of similar size at 20%, 40%, 60%, and 80% after ranking all the provinces and municipalities by the rates of hypertension prevalence). 0–20% quintile = 1, 20–40% quintile = 2, 40–60% quintile = 3, 60–80% quintile = 4, 80–100% quintile = 5. *p < 0.05, **p < 0.01, ***p < 0.001.
