Note. Descriptive statistics for continuous variables. Nutritional parameters and PN formulation characteristics in study patients during phases 2 and 3. Nutritional parameters are presented with all study patients and with removal of three outlier patients (see text). PN intakes are express as g/day, g/kg/day and infusion rate.
