Also there are plans to carry out a multivariate analysis. There will be a quantification of the adjusted effect on mortality due to the introduction of PROGALIAM by a Cox Proportional Hazards model. It will be defined the best model to predict this adjusted event by independent variables which can demonstrate an impact on death outcome in the univariate model and by those independent variables in which significant differences are observed between the pre and post PROGALIAM population. The investigators will verify if the implementation of the PROGALIAM is an independent predictor of survival and the impact that generates in the model.
