	Model A	Model B	Model C		Model D		Model E		Model F		Model G
				Diff. with B (%)*		Diff. with B (%)*		Diff. with B (%)*		Diff. with B (%)*		Diff. with B (%)*
Childhood epilepsy	4.23	4.34	4.26	2.4	4.30	1.2	4.34	0	4.29	1.5	4.30	1.2
95% CI	(2.23–8.02)	(2.29–8.24)	(2.25–8.09)		(2.27–8.15)		(2.29–8.24)		(2.26–8.13)		(2.26–8.15)

^*(The contribution of each factor was measured by the percentage reduction in the odds ratio of epilepsy compared to Model B by using formula (OR Model B – OR Model C/D/E/F/G)/(OR Model B –1).

Model A = Adjusted for maternal epilepsy.

Model B = Adjusted for Model A+maternal age and parity.

Model C = Adjusted for Model B+mode of delivery.

Model D = Adjusted for Model B+Apgar score ≤6.

Model E = Adjusted for Model B+ART.

Model F = Adjusted for Model B+Major congenital anomalies.

Model G = Adjusted for Model B+umbilical cord length.
