Age ≥ 60 | 0.58 | 0.37 | 0.72 (0.70–0.74) | 0.57 (0.55–0.59) | 0.04 (0.02–0.06) | 0.07 (0.05–0.09) | 0.145 |

- Model is adjusted for baseline age (quartile), sex, systolic blood pressure (quartile), diastolic blood pressure (quartile), body mass index (quartile), triglyceride (quartile), low-density lipoprotein cholesterol (quartile), high-density lipoprotein cholesterol (quartile), estimated glomerular filtration rate (quartile), uric acid (quartile), current smoking, current drinking, and anti-hypertensive drug. The P value is calculated by t-test of the two cross-lagged standard regression coefficients of baPWV and HbA1c
- BaPWV, branchial-ankle pulse wave velocity; HbA1c, glycated hemoglobin
