(a) Correlation between log VPT and log PWVao in diabetes and nondiabetes participants. Data analysed by Pearson's correlation test. In nondiabetes participants, log VPT do not correlate with log PWVao in zero-order (r = 0.13, p = 0.313) and age and gender partial (r = −0.1, p = 0.444) correlations. In diabetes patients, log VPT correlated with log PWVao in zero-order (r = 0.14, p = 0.013) and age and gender partial (r = 0.16, p = 0.004) correlations. (b) Correlation between log VPT and CAVI in diabetes and nondiabetes participants. Data analysed by Pearson's correlation test. In nondiabetes participants, log VPT do not correlate with CAVI in zero-order (r = 0.16, p = 0.186) and age and gender partial (r = −0.05, p = 0.69) correlations. In diabetes patients, log VPT correlated with log CAVI in zero-order (r = 0.21, p = 0.002) and nonsignificant in age and gender partial (r = 0.12, p = 0.067) correlations.
