Body

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.

Comparison of BIA components in the control group with average (Avg.) values in the HD group and changes in the BIA components between pre- and post-HD

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.

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

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)”.
