Figure 1From: Early versus late parenteral nutrition in ICU patients: cost analysis of the EPaNIC trialCost tree (cost allocation in the form of a decision tree). Costs are allocated by studied randomly assigned treatment (first branch), by the acquisition of a new infection (second branch), and by prolonged intensive care unit (ICU) stay, defined as an ICU stay beyond 8 days (third branch). The percentages represent the proportion of patients for the entire study population in each branch. The costs in euros (EUR) represent the total costs for all patients in each branch and - between brackets - mean cost per patient. Costs reported in euros are rounded at zero decimals. Early PN, parenteral nutrition administered during the first week of critical illness when enteral nutrition is insufficient; Late PN, no parenteral nutrition administered before day 8 of critical illness.Back to article page
