The comparison of biologically active factors profiles of caesarean section and physiological delivery-derived amniotic membrane samples. The concentration of ANG, TIMP-1, Serpin E1, and IGFBP1-3 in amniotic membrane extracts is expressed in units of optical density

	Caesarean section Mean ±SD/median (Min.-max.)	Physiological delivery Mean ±SD/median (Min.-max.)
ANG	1.20 ±1.0/0.96 (0-2.56)	2.24 ±1.42/2.07 (0.62-4.61)
IGFBP-1	1.41 ±0.52/1.3 (0.82-2.37)	1.41 ±0.38/1.39 (0.99-2.20)
IGFBP-2	0.62 ±0.38/1.02 (0.3-1.2)	1.17 ±0.92/1.02 (0-2.85)
IGFBP-3	0.6 ±0.39/0.66 (0-0.97)	1.19 ±0.79/1.1 (0.27-2.58)
Serpin E1	1.13 ±0.58/0.91 (0.59-2.09)	1.12 ±0.63/0.87 (0.5-2.45)
TIMP-1	1.84 ±1.01/1.39 (1.13-3.72)	2.14 ±0.69/2.17 (1.2-3.11)
