Two models (Models 1–2) were used in the multivariate logistic regression analysis including presence/absence of fascioliasis as dependent variable:

- Model 1 including consumption of broccoli, spinach, lettuce, radish, corncob, alfalfa juice and watercress as independent variables.

- Model 2 including consumption of rice, flat maize pancake, beans and watercress & potato pancake as independent variables.
