Fig. 2
Repeated measures correlation plots between age and pulse wave velocity (PWV) indices (Panel A: hbPWVeq1; Panel B: hbPWVeq2; Panel C: baPWV). Lines represent intra-individual linear regression lines for each participant. DF, degrees of freedom; rrm, the coefficient of repeated measures correlation. Panel (D) presents the comparison of the age-related regression slopes of PWVs. (a) P < 0.0001 vs. <35 years of the initial age group. (b) P < 0.0001 vs. 35-39 years of the initial age group. (c) P < 0.0001 vs. 40–44 years of the initial age group. (d) P < 0.0001 vs. 45-49 years of the initial age group. *P < 0.0001 vs. baPWV. Error bars indicate 95% confidential interval
