Logistic regression (model: binary logit; optimization: Fischer’s scoring) with stepwise elimination to indicate only significant variables and two-way-interactions regarding the composite outcome need for catecholamines AND need for invasive ventilation AND fatal outcome for patients with enterococcal or nonenterococcal bacteremia. Reciprocal dependence of the three parameters of the composite outcome had been proven by crosstabs (data not shown). Significance was assessed by chi-square testing
