Time course of fluid resuscitation variables. a Daily fluid input. b Daily fluid output. c Daily fluid balance. d Cumulative fluid balance. e Hydration level. Means and 95% confidence intervals of pertinent variables for the first week after ICU admission. The fluid volume and bioelectrical impedance analysis variables of the BIA group are depicted with a blue full line, and those of the TRD group are depicted with a red dotted line. *P < 0.05, day-by-day pairwise comparison between the BIA and TRD groups.
