Goal-directed fluid therapy using stroke volume variation on length of stay and postoperative gastrointestinal function after major abdominal surgery-a randomized controlled trial

Table 4 Comparison of primary outcomes between two groups

	Control group (n = 50)	GDFT group (n = 50)	P value
Time to first flatus, [hours, median (IQR)]	39.4(24.9–67.5)	28.2(9.2–48.0)	0.009^*
Time to first tolerate oral diet, [days, median (IQR)]	6.0(5.0–9.3)	4.0(2.7–6.0)	< 0.001^*
The length of hospital stays, [day, mean ± SD]	12.0 ± 4.6	9.0 ± 5.8	0.001^*

Data are presented as mean ± SD (standard deviation), or median (IQR, interquartile ranges). Data were compared using Mann–Whitney U-test or Student’s t-test as appropriate
