The independent relationship between selected clinical variables including class of antihypertensive medications and the dependent variable uncontrolled hypertension on 1–2 antihypertensive medications are shown as multivariable odds ratios and 95% confidence intervals for each of the three NHANES periods. The reference group is all hypertensive patients that reported taking 1–2 BP medications. Confidence intervals that do not cross the line of identity (1.0) are considered statistically significant.
