Table 3 Survival hazard ratio (HR) estimated in the multivariable Cox Proportional-Hazards model with age, weight at admission, sepsis type, antibiotic management cluster, and the presence of RD as potential determinants. Cluster 3 was chosen as reference because it accounts for the cluster outside the protocol antibiotic lines
