Table 2. Amniotic fluid index (AFI) before and after hydration at 90 min and 48 h in the study and control groups .

	Study group (n = 10)	Control group (n = 10)	Mean difference (CI %95)	statistical Indicator
Baseline AFI	4.6 (0.3)	4.4 (0.5)	0.2(-0.2,0.6)	P=0.31, t=1.03, df=22
AFI at 90 min	3.5 (1.33)	2.9 (1.0)	0.6(-0.4,1.6)	P=0.22, t=1.59, df=22
ΔAFI (base line, 90 min)	-1.12 (1.24)	-1.5 (1.0)	0.2(-2.9,3.5)	P=0.39, t=0.86, df=22
AFI at 48 h	3.97 (3.0)	3.7 (1.56)	0.4(-0.5,1.35)	P=0.86, t=1.03, df=22
ΔAFI (base line, 48 h)	-0.59 (2.8)	-1.0 (1.45)	0.4(-2.6,3.4)	P=0.77, t=0.29, df=11

All the values are presented in centimeters as mean (SD).

AFI: Amniotic fluid index; ΔAFI: Difference between AFI at the two mentioned times.
