Figure 1. 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.

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.
