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).

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

The ECW/TBW data of Table 2 should be corrected as follows.

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