Carotid ultrasound measurements in patients with diabetes and healthy controls.

Data are mean (95% confidence interval). IMT, Intima-media thickness; PI, pulsatily index; RI, resistive index; PSEM, pressure-strain elastic modulus.

数据以均值（95%置信区间）表示。内膜中层厚度（Intima-media thickness，IMT）；搏动指数（pulsatility index，PI）；阻力指数（resistive index，RI）；压力应变弹性模量（pressure-strain elastic modulus，PSEM）。
