Early enteral nutrition in critical illness: a full economic analysis using US costs.

7 Patients receiving early EN demonstrated a strong trend towards a reduction in duration of ICU stay (−2.3 days [95% CI −4.8 to 0.1 days, P = 0.06, I 2 = 0%]) ( Figure 1 ) and duration of mechanical ventilation (−2.5 days [95% CI −5.1 to 0.1 days, P = 0.06, I 2 = 0%]) ( Figure 2 ); however, the hospital length of stay did not differ between the groups (−2.5 days [95% CI −16.0 to 11.0 days, P = 0.72, I 2 = 0%]) ( Figure 3 ).
