The accuracy of the model was evaluated by calculating average percentage deviation (APD) between calculated and observed values. The obtained overall APD (S.D.) were 1.2 ( 0.9) and 2.2 ( 1.8) %, respectively for correlative and predictive analyses.https://daru.tums.ac.ir/index.php/daru/article/view/259https://daru.tums.ac.ir/index.php/daru/article/download/259/259
