Brachial-Ankle Pulse Wave Velocity Predicts New-Onset Hypertension and the Modifying Effect of Blood Pressure in a Chinese Community-Based Population

Table 4

Interactive effect between baseline SBP and baPWV on the risk of incident hypertension or the SBP level at follow-up.

baPWV, brachial-ankle pulse wave velocity; SBP, systolic blood pressure; OR, odds ratio; CI, confidence interval. Variables in multivariate adjusted models, age, sex, body mass index, current smoking, current drinking, baseline SBP and estimated glomerular filtration rate, diabetes mellitus, dyslipidemia, history of cardiovascular disease, hypoglycemic agents, and lipid-lowering agents. value for interaction trend test.
