Agreement and device-specific calibration of a single-frequency and a multi-frequency segmental bioelectrical impedance analyzer against dual-energy X-ray absorptiometry for appendicular skeletal muscle mass: a two-center method-comparison study with external validation
这项两中心研究表明,虽然单频和多频生物电阻抗分析仪与双能X射线吸收法相比表现出系统性的、特定设备的偏差,但应用特定设备的校准方程能显著提高其在外部验证中的准确性和低肌肉量分类的准确性,这强调了在未经调整的情况下,BIA和DXA不能互换使用。
