FIGURE 2.
Path diagram showing full mediation of reduction of night-time carotid femoral pulse wave velocity regarding the relationship between different treatment groups and smoothness index of central SBP. Data were expressed as estimate [standard error]. Adjusted covariates: baseline age, sex, brachial SBP, smoking or drinking status, height and waist circumference. AcfPWV, ambulatory carotid femoral pulse wave velocity; HCTZ, dihydrochlorothiazide; SI, smoothness index. ∗P < 0.05; P for indirect effect was calculated using Sobel test.
