Kim, Choi, Shim, Lee, Heo, Joo, Yoon, and Oh: Changes in bioimpedance analysis components before and after hemodialysis [Volume 37, Issue 4, December 2018, Pages 393–403]
The authors would like to publish this corrigendum to correct the data in Table 2 of the above article (https://doi.org/10.23876/j.krcp.18.0035).
The ECW/TBW data of Table 2 should be corrected as follows.

Data are presented as mean ± standard deviation.

BIA, bioimpedance analysis; BMI, body mass index; BMR, basal metabolic rate; ECW, extracellular water; HD, hemodialysis; ICW, intracellular water; LTI, lean tissue index; PBF, percent body fat; TBW, total body water; WHR, waist-hip ratio.

a P value pre-HD compared with post-HD, and

b P value of the control group compared with Avg. HD.

* P < 0.01,

P < 0.05.

And also, the authors would like to clarify a product name. “S720 device” in the article means “Inbody 720 (Inbody, Seoul, Korea)”.
