Total GWG, intervention period weight gain, and birth weight of infants born to term by women in the probiotic and placebo groups

	ITT			PP
	Probiotic n = 20	Placebo n = 23	P value	Probiotic n = 15	Placebo n = 16	P value
Total GWG, kg (mean ± SD)	12.7 ± 5.3	13.1 ± 5.8	0.82	11.9 ± 4.9	13.0 ± 4.2	0.46
Intervention period weight gain, kg (mean ± SD)	10.2 ± 3.4	10.0 ± 4.2	0.87	9.9 ± 3.4	10.8 ± 3.4	0.44
Infant birth weight of term-born infants, g (mean ± SD)	3608 ± 475	3640 ± 454	0.82	3554 ± 487	3658 ± 428	0.52

GWG, gestational weight gain; ITT, intention-to-treat; PP, per protocol. Total GWG = weight in week 36–37 minus prepregnancy weight. Intervention period weight gain = weight in gestational week 36–37 minus weight in gestational week 16–20 (baseline). Between group differences was done using a 2-sample t-test.
