Figure 2. Forest plot of the effect of baseline systolic blood pressure on annual progression of arterial stiffness by meta‐analysis of standardized β regression coefficients from analyses adjusted for demographic variables and stratified by age.

A, Mean age >50 years old. B, Mean age <50 years old. C, Including studies reporting effects on progression of carotid‐femoral pulse wave velocity (cfPWV). D, Including studies reporting effects on brachial‐ankle pulse wave velocity (baPWV). Effects were analyzed by both fixed and random effects meta‐analysis weighted by the inverse variance. CIhigh indicates CI upper limit; CIlow, CI lower limit; I‐sq, I² statistic; N, number of subjects; P‐Het, P value for heterogeneity; and StdBeta, standardized regression coefficient.
