AB  - Post-dialysis urea rebound (PDUR) has been attributed mostly to redistribution of 
      urea from different compartments, which is determined by variations in regional 
      blood flows and transcellular urea mass transfer coefficients. PDUR occurs after 
      30-90min of short or standard hemodialysis (HD) sessions and after 60min in long 
      8-h HD sessions, which is inconvenient. This paper presents adaptive network 
      based on fuzzy inference system (ANFIS) for predicting intradialytic (Cint) and 
      post-dialysis urea concentrations (Cpost) in order to predict the equilibrated 
      (Ceq) urea concentrations without any blood sampling from dialysis patients. The 
      accuracy of the developed system was prospectively compared with other 
      traditional methods for predicting equilibrated urea (Ceq), post dialysis urea 
      rebound (PDUR) and equilibrated dialysis dose (eKt/V). This comparison is done 
      based on root mean squares error (RMSE), normalized mean square error (NRMSE), 
      and mean absolute percentage error (MAPE). The ANFIS predictor for Ceq achieved 
      mean RMSE values of 0.3654 and 0.4920 for training and testing, respectively. The 
      statistical analysis demonstrated that there is no statistically significant 
      difference found between the predicted and the measured values. The percentage of 
      MAE and RMSE for testing phase is 0.63% and 0.96%, respectively.
