Following the publication of the original article [1] the authors noticed that the published Figs. 2 and 3 are incorrect. These were not replaced during corrections stage.

The original article [1] has been updated.

Below are the correct Figs. 2 and 3.

Fig. 2

Simple linear regression for estimating thigh skeletal muscle volume (SMV) measured by magnetic resonance imaging (MRI) with 50-kHz bioelectrical impedance index (BI) (A) and intracellular water (ICW) index (B). A y = 54.8 × 50 kHz BI index + 578.3; R² = 0.548; SEE = 239.0 cm³, 9.4%. B y = 119.5 × ICW index + 927.5; R² = 0.703; SEE = 193.7 cm³, 7.6%

Fig. 3

Simple linear regression for estimating quadriceps skeletal muscle volume (SMV) measured using magnetic resonance imaging (MRI). Simple linear regression relationship between quadriceps SMV using 50-kHz bioimpedance index (BI) (A), intracellular water index (ICW) (B), and muscle thickness index (C). A y = 36.1 × 50 kHz BI index + 545.7; R² = 0.433; SEE = 198.5 cm³, 10.8%. B y = 78.4 × ICW index + 779.5; R² = 0.551; SEE = 176.6 cm³, 9.6%. C y = 10.3 × muscle thickness index + 35.3; R² = 0.543; SEE = 178.1 cm³, 9.7%
