Figure 3From: The novel application of artificial neural network on bioelectrical impedance analysis to assess the body composition in elderly The relationship between the number of neurons in the input layer of the BP-ANN models and the determination coefficients of the FFM values measured by DXA are shown for the modeling group. SD, standard deviation; RMSE, root mean square error; BR r2, determination coefficients of predictive values by Bayesian Regularization and the FFM values measured by DXA.Back to article page
