Effect on longitudinal growth and anemia of zinc or multiple micronutrients added to vitamin A: a randomized controlled trial in children aged 6-24 months

Table 3 Change in hemoglobin in all subjects stratified by presence of anemia at baseline

	n	Mean change in hemoglobin g/dL, mean (95% CI)¹ [n per treatment arm]
		Vitamin A only	Vitamin A + zinc	Multivitamins	Overall P²
All subjects	210	0.59 (0.22, 0.97)^b [68]	0.17 (-0.20, 0.54)^a [71]	0.62 (0.26, 0.98)^b [71]	0.06
Anemic at baseline	166	0.99 (0.56, 1.41) [52]	0.49 (0.07, 0.91) [54]	0.93 (0.54, 1.31) [60]	0.10
Not anemic	44	-0.92 (-1.81, -0.02) [16]	-1.12 (-2.00, -0.25) [17]	-0.48 (-1.56, 0.59) [11]	0.49

¹ Adjusted for baseline hemoglobin and cohort
² ANOVA F-test
Values in the same row with different superscripts are significantly different from each other (P < 0.05)
