Table 1 Demographic data

	Group L (n = 28)	Group E (n = 26)
Age (years)	35.93 ± 2.54	35.15 ± 4.76
Weight (kg)	66.56 ± 8.74	71.18 ± 6.69
Height (cm)	159.48 ± 6.10	160.65 ± 7.67
Body mass index (kg/m²)	26.17 ± 3.09	27.67 ± 4.00
ASA class (I / II)	7 / 21 (25 / 75)	6 / 20 (23 / 77)
Status of practitioners (R1 / R2 / R3 / R4 / Specialist)	4 / 8 / 2 / 6 / 8	4 / 8 / 2 / 7 / 5

Values are either the mean ± SD or the number of patients (%). Group L used a loss of resistance technique in the epidural cesarean section while group E used electrical epidural stimulation combined with a loss of resistance technique. There was no significant difference between the two groups. ASA class refer to American Society of Anesthesiologists physical status. R1, R2, R3 and R4 refer to first-, second-, third- and fourth-year residents
