Change in serum ferritin, iron, and transferrin over the intial 3 mo of treatment as a result of TE treatment [i.e., combined effects of treatments 1 and 2 (no TE) vs. 3 and 4 (with TE), respectively]

	Estimate	P Value	Interaction (P Value)
3-Mo Δferritin, ng/ml	−132 ± 32	0.002	0.450
3-Mo Δiron, μg/dl	−3 ± 11	NS
3-Mo Δtransferrin, mg/dl	11 ± 8	NS
3-Mo Δtransferrin saturation, %	−1.0 ± 4.6	NS

Values represent means ± SE. The interaction test was performed only when a significant effect was observed.
