§Values are represented as mean ± standard error for normal distributed data; otherwise, as median (25%–75% interquartile). * P < 0.05, compared to DKD patients with normal SUA; ∆ P < 0.05, compared to normal control. Ultrasound parameters abbreviations used are as follows: IMAX, maximum intensity; RT, rise time; TTP, time to peak; mTT, mean transit time; AUC, the area under the perfusion curve; AUC1, area under the ascending curve; AUC2, area under the descending curve.
