Changes in serum hemoglobin levels in intervention and control groups.

Hemoglobin level (gm/dl)	Intervention group (n = 112/224*)	Control group (n = 100/200*)	p-value
Unadjusted (COR)
Total Hb change, gm/dl (95% CI)	0.23 (0.17,0.29)	0.11 (0.2, 0.18)	0.016
Mean difference, gm/dl (95% CI)	0.12 (0.08, 0.21)	Reference
Rates of Hb change, gm/dl/week (95% CI)	0.015 (0.011, 0.07)	0.006 (0.003, 0.009)	<0.0001
Adjusted (aOR)**
Total Hb change, gm/dl (95% CI)	0.21 (0.13,0.22)	0.10 (0.07, 0.13)	<0.0001
Mean difference, gm/dl (95% CI)	0.11 (0.09, 0.15)	Reference
Rates of Hb change, gm/dl/week (95% CI)	0.02 (0.01, 0.09)	0.004 (0.002, 0.12)	<0.0001
