Note: Response variable was presence (1) or ausence (2) of T. cruzi. Explicative variables are the ones shown in the table. A stratified simulation (1000 samples) was made for the response variable (T. cruzi presence) in each executed model. Wald estimator was used to determine the OR 95% confidence intervals
*Most statistically significant variables
