Cox and Snell R and Nagelkerke R were applied to determine the variance explained with the factors. The global percentage of the model and the χ²-test of the omnibus were used for the significance of the factors, as well as the adjusted OR with its corresponding 95% confidence intervals.
Para la determinación de la varianza explicada con los factores, se aplicó R de Cox y Snell y R de Nagelkerke, el porcentaje global del modelo y la prueba de χ² de ómnibus para la significancia de los factores y el OR ajustado con sus intervalos de confianza al 95%.
