From: Associations between Blood Pressure Indices and Brachial–ankle Pulse Wave Velocity in Treated Hypertensive Adults: results from the China Stroke Primary Prevention Trial (CSPPT)

Figure 2

Association between BP indices and baPWV. (A) SBP and baPWV; (B) DBP and baPWV; (C) PP and baPWV; (D) MAP and baPWV. The smooth curve fitting presented linear associations between all BP indices and baPWV among participants with treated hypertension. The solid line and dashed line represent the estimated values and their corresponding 95% confidence intervals (CI). Abbreviations: baPWV, brachial–ankle pulse wave velocity; BP, blood pressure; SBP, systolic blood pressure; DBP, diastolic blood pressure; PP, pulse pressure; MAP, mean arterial pressure. Adjustment factors included age, sex, center, MTHFR C677T polymorphisms, treatment group, antihypertensive treatment, BMI, smoking status, and alcohol consumption, RHR, TC, HDL-cholesterol, TG, FPG, creatinine, homocysteine, uric acid.
