The measurement error between VFA by CT and dual BIA among patients with type 2 diabetes. The measurement of the VFA both by CT and by dual BIA was performed on the same day. The VFA by dual BIA was estimated after an overnight fast and urination. Then, before lunch, CT was performed, and the VFA at the umbilical level was determined by two independent researchers using the image analysis software. The measurement error between the two methods was expressed as % measurement error, which was calculated as follows: % measurement error = {(VFA-CT − VFA-BIA)/VFA-CT} × 100(%). a The distribution of % measurement error. b The % measurement error among different levels of BNP. Patients were divided into two groups according to their levels of BNP (cutoff value: 100 pg/mL). Data are expressed as mean ± standard deviation. *P < 0.05
