A corrigendum on
Development and cross-validation of a predictive equation for fat-free mass in Brazilian adolescents by bioelectrical impedance

By Costa, R. F., Silva, A. M., Masset, K. V. d. S. B., Cesário. T. d. M., Cabral, B. G. d. A. T., Ferrari, G., and Dantas, P. M. S. (2022). Front. Nutr. 9:820736. doi: 10.3389/fnut.2022.820736

In the original article, there was a mistake in Table 4 as published. The article included a table referring to another mathematical model, which does not refer to this study. The corrected Table 4 appears below.

TABLE 4
www.frontiersin.org

Table 4. Regression model for the prediction of fat-free mass (kg).

In the original article, there was an error on page 5 in the section Results. In the presentation of the mathematical model for FFM estimation, the word “Fri” appears instead of the word “Sex.”

The corrected mathematical model included is presented below:

FFM=− 17.189+0.498 (Height2/Resistance)+0.226 Weight +0.071 Reactance         −  2.378 Sex+0.097 Height +0.222 Age

Sex: male = 0; female = 1

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
