In Tables 3 and 4, the REE data are provided as mean measured REE (in kcal/day), the percentage of accurate underpredictions and overpredictions, the percentage bias, the maximum values found for negative error (underprediction) and positive errors (overprediction), and the RMSE (in kcal/day). The percentage accurate predictions varied between equations from 74% to 12%. The bias for equations varied from -19.8% to 10.8%, and the RMSE varied from 174 to 434 kcal/day. The RMSE is based on an average value of squared differences (predicted minus measured value) for individuals; therefore, individual values can be much worse as shown by maximum negative and maximum positive error.
