Figure 1.

Estimated associations between education (reference: less than high school) and systolic BP. Figure shows estimated coefficients and 95% confidence intervals on education variables (reference: less than high school) from OLS and UQR models of systolic BP that include age, age-squared, sex/gender, and race/ethnicity as covariates. Full numeric results are provided in Table 3. BP = blood pressure, measured in millimeters of mercury (mmHg); OLS = ordinary least squares; UQR = unconditional quantile regression.
