Changes in hemoglobin level from baseline

Parameter (vs. baseline)	Week	PCG^a,b (n = 14–15)	FE^a (n = 15)	FEMT^a (n = 15)	P^c
Parameter (vs. baseline)	Week	PCG^a,b (n = 14–15)	FE^a (n = 15)	FEMT^a (n = 15)	FEMT vs FE	FEMT vs PCG	FE vs PCG
Hemoglobin	2	−0.4 (0.5)	0 (0.7)	0 (0.4)	0.999	0.064	0.069
	4	−0.5 (0.5)	−0.3 (0.6)	0.2 (0.6)	0.054	0.007**	0.657
	6	−0.4 (0.6)	−0.1 (0.5)	0.2 (0.6)	0.215	0.008**	0.323

Bold values represent the significantly different (*P < 0.05, ** P < 0.01)

^aAll values are expressed as the mean (SD). PCG placebo control group; FE intervention group receiving 6 mg iron alone once daily; FEMT intervention group receiving 200 mg methionine, 400 mg threonine, and 6 mg iron once daily

^bThe sample size in the PCG at week 2 and 4 was n = 14 due to missed visits

^cThe Tukey–Kramer test was used for comparison between the three groups. The test statistics are marked with **P < 0.01
