Variables	Early labor	End of the second stage of labor	2 h postpartum	24 h postpartum	P value
IVCe, cm	1.63(0.49)	1.73(0.50)	1.89(0.35)^a	1.82(0.58)^a	0.023
IVCi, cm	1.21(0.31)	1.47(0.30)^a	1.47(0.39)^a	1.19(0.31)^bc	0.004
IVC-CI, %	25.29(9.44)	12.96(5.88)^a	20.39(8.59)^b	31.88(12.26)^abc	< 0.001

Values reported as median (interquartile range) as appropriate
IVCe: end expiratory inferior vena cava diameter, IVCi: end inspiratory inferior vena cava diameter, IVC-CI: inferior vena cava collapsibility index
^a Compared with the early labor, the difference is statistically significant, and after q test with Holm correction, P < 0.05
^b Compared with the end of the second stage of labor, the difference is statistically significant, and after q test with Holm correction, P < 0.05
^c Compared with 2 h postpartum, the difference is statistically significant, and after q test with Holm correction, P < 0.05
