Table 2 Summary statistics on the outcomes of labour and delivery by intervention groups

	Study group (n = 362)	Control group (n = 362)	P value
Length of labour (hours, median, range)	1.5 (0.16–6.1)	3.05 (0.4–11.7)	0.0001
Postpartum haemorrhage (over 500 ml) (number, %)	8 (2.5%)	18 (5%)	0.07
Use of oxytocin (number, %)	18 (4.9%)	20 (8.8%)	0.999
Use of pain relief (number, %)	13 (3.6%)	12 (3.3%)	0.999
Apgar score < 7 at 1 min (number, %)	2 (0.5%)	1 (0.25%)	0.999
Apgar score < 7 at 5 min (number, %)	1 (0.25%)	0 (0%)	0.999
Emergency caesarean section (number, %)	12 (3.3%)	86 (24%)	0.0001
Fetal distress (number, %)	25 (7%)	36 (10%)	0.181

The difference in the length of labour between two groups was performed with Mann-Whitney U-test. The differences in the proportion of PPH, use of pain relief, use of oxytocin, apagr score less than 7 at 5 min and emergence caesarean section were performed with Chi-square test
