Table 2B:

Adjusted risk for low hemoglobin deferral at follow-up visits in female donors by age and iron status at enrollment visit

	Adjusted ORs*	95% C.I.
Age
16yo vs 19–49yo	2.3	1.2, 4.4
17yo vs 19–49yo	1.5	0.9, 2.5
18yo vs 19–49yo	1.6	0.8, 3.3
Ferritin at enrollment visit
< 12 vs ≥ 26 ng/mL	5.9	3.9, 8.8
12 to 25 vs ≥ 26 ng/mL	2.9	1.9, 4.5

^*Adjusted ORs from repeated measures logistic regression model also controlling for race, weight, donation frequency, donation interval, and blood center.
