This final model showed that only the type of surgery endoprothesis was a protector factor, in spite of presenting greater relative risks for mortality. Having received GA, being older than 77, pre-surgery stay greater than 2 days and having presented CV IOP instability, none of the explanatory or independent or fuzzy variables behaved as independent factors or were significantly associated for mortality, meaning that irrespective of being risk factors or protectors, their statistical significance was not admitted in the final model.
Este modelo final mostró que sólo el tipo de cirugía endoprótesis se comportaba como factor protector, a pesar de presentar mayores riesgos relativos para mortalidad; el haber recibido anestesia general, tener más de 77 años, una estancia prequirúrgica mayor de 2 días y haber presentado inestabilidad cardiovascular durante la cirugía, ninguna de las variables explicativas ni independientes o de confusión se comportaron como factores independientes o asociados significativos para mortalidad, ya fuese como factores de riesgo o protectores, su significancia estadística no los admitió dentro del modelo final.
