Background: The ratio of bioimpedance in the right leg (rl-RBI) may be helpful in adjusting dry body weight (DBW) in new hemodialysis (HD) patients. Methods: rl-RBI was calculated as follows: rl-RBI= impedance at 50 kHz/impedance at 500 kHz, as measured by bioimpedance spectroscopy (BIS). Theoretically, rl-RBI is inversely related to extracellular water. A reference range of rl-RBI was obtained from 137 chronic but stable HD patients already achieving DBW. In 34 new HD patients (females: males= 16: 18; age 49±12 years) …
