Notes:
†
Average fluid intake per day = total amount of fluid/total duration of fluid intake in a day;
*
The median (IQR) was calculated only in those patients who received each type of fluid;
**
Comparing the median of average daily volume between ≤5% and >5%;
‡
Percent of calculated patients who received each type of fluid or total population.
Abbreviations: FFP, fresh frozen plasma; HES, hydroxyl-ethyl starch; ICU, intensive care unit; IQR, interquartile range.
