To the Editor,
There was an error in our published article titled “Total energy intake according to the level of skeletal muscle mass in Korean adults aged 30 years and older: an analysis of the Korean National Health and Nutrition Examination Surveys (KNHANES) 2008–2011” Nutrition Research and Practice 2018;12(3):222–232; http://dx.doi.org/10.4162/nrp.2018.12.3.222; pISSN 1976-1457 eISSN 2005-6168.
We made a mistake in presenting an equation for SI calculation on page 223. The correct equation for calculating SI should be as follows.
SI=total appendicular muscle mass (kg)/BMI (kg/m2)
These errors did not influence the subsequent analyses/statistics at all. Thus, changes for these errors do not impact the conclusions of the paper. The authors apologize for any inconvenience this mistake may have caused.
