a) The risk of late miscarriage and preterm birth, according to GDM status at inclusion in 772/773 women.
	GDM at inclusion (WHO 1999)		p-value	GDM at inclusion (WHO 2013)		p-value
	Yes	No		Yes	No
N (%)	77 (10)	695 (90)		160 (21)	613 (79)
Late miscarriage	4 (5.2)	7 (1.0)	0.003	6 (3.8)	5 (0.8)	0.005
Preterm birth	3 (3.9)	44 (6.3)	0.40	7 (4.4)	40 (6.5)	0.31
b) Determinants of late miscarriage, logistical regression.
	Late miscarriage
	Univariable			Multivariable
	OR (95% CI)		p-value	OR (95% CI)		p-value
Maternal age	1.13 (0.99–1.29)		0.07	1.13 (0.98–1.32)		0.10
Maternal BMI	1.06 (0.98–1.16)		0.14	1.06 (0.96–1.16)		0.24
Smoking	0.0*		1.00	0.0*		1.00
Randomization	2.65 (0.70–10.05)		0.15	2.56 (0.66–10.00)		0.18
Fasting glucose, incl.	1.31 (0.37–4.6)		0.67	0.46 (0.12–1.8)		0.27
2-hour glucose, incl.	1.71 (1.24–2.36)		<0.01	1.69 (1.20–2.39)		0.003
Total model (enter)						p = 0.009

OR = odds ratio, CI = confidence interval.

*Confidence interval cannot be computed, as none of the women with late miscarriage did smoke (Fisher’s exact test p = 0.65). Multivariable logistical regression using model: Enter.
