Systolic (A) and diastolic (B) blood pressure according to antihypertensive medication intensity. Data are presented as mean (95% confidence interval). Models were adjusted for sex (male, female), age (years), annual household income (< $10,000; $10,000-$24,999; $25,000-$49,999; $50,000-$74,999; $75,000-$99,999; $100,000-$149,999; $150,000-$199,999; > $200,000), body mass index (kg/m²), smoking status (never/ever/current), alcohol consumption (grams per day), energy intake (kcal per day), physical activity level (low/moderate/high), self-reported history of high blood cholesterol (no/yes), and DASH score. The number of antihypertensive medication classes was treated as a categorical variable in this model (0; 1; 2; 3+). Groups with different superscript letters are statistically different (Tukey-Kramer’s multiple comparison test, P < 0.05). DASH, Dietary Approaches to Stop Hypertension.
