Pages 1542-1558: A. De Lorenzo, A. Andreoli, J. Matthie, and P. Withers. "Predicting body cell mass with bioimpedance by using theoretical methods: a technological review." The authors noticed several mistakes that do not affect the results but should be corrected nevertheless. On p. 1545: the calculation of f_c following modeling was incorrect; hence, the corrected f_c values are reprinted below in Table 2. On p. 1553: in Fig. 14, the correct f_c values are 124 kHz predialysis and 71 kHz postdialysis; for Table 6, n should be 48, not 73. On p. 1554, left column: line 10, the mean reported for f_c should be changed from ~60 kHz to 44 kHz; line 15, the range should read "from 32 to 65 kHz" instead of "from 43 to 110 kHz." On p. 1554, right column: line 29, a mean increase of C_m reported as 64% should read 50%.
