Table 3 The final predictive BIA equation for ALM on Korean older people

From: Two-megahertz impedance index prediction equation for appendicular lean mass in Korean older people

Final Predictive Equation (n = 195)
Measured ALM = 17.44 ± 3.71
Predicted ALM = 0.247ZI@2 MHz + 1.254sexM1F0 + 0.067Xc@5 kHz + 1.739
R = 0.965, Adusted R2 = 0.930, SEE = 0.97 kg, SR: Excellent (M), Very good (F)
CV = 5.6%, VIF: ZI@2 MHz = 3.54, SEXM1F0 = 3.57, Xc@5 kHz = 1.07
Predicted ALM = 17.45 ± 3.58
