§Delta eGFR (mLmin⁻¹per 1.73 m²) = 12-month eGFR − baseline eGFR = annual eGFR change.
¶eGFR change rate (%) = 12-month eGFR − baseline eGFR/baseline eGFR = annual eGFR change rate (%).
ba-PWV: brachial-ankle pulse wave velocity (m/s); SBP: systolic blood pressure (mmHg); PP: pulse pressure (mmHg); TBI: toe-brachial index; ^∗∗𝑃<0.01; ^∗𝑃<0.05; n = 577.
