BABY HUG (ClinicalTrials.gov, NCT00006400) was a NHLBI\u2010NICHD supported randomized phase III placebo\u2010controlled trial of hydroxyurea (HU) in infants (recruited at 9\u201318 months) unselected for clinical severity with sickle cell anemia. This secondary analysis of data from BABY HUG examines the influence of anemia on the incidence of sickle cell related complications, and the impact of hydroxyurea therapy in altering these events by comparing children with lower (&lt;25th percentile) and higher (&gt;75th percentile) hemoglobin concentrations at study entry.<\/jats:p><\/jats:sec><jats:sec><jats:title>Procedure<\/jats:title><jats:p>Infants were categorized by: (1) age\u2010adjusted hemoglobin quartiles as determined by higher (Hi) and lower (Lo) hemoglobin concentrations at study entry (9\u201312 months old: &lt;8.0 and &gt;10.0\u2009gm\/dL; 12\u201318 months old: &lt;8.1 and &gt;9.9\u2009gm\/dL) and (2) treatment arm (hydroxyurea or placebo). Four subgroups were created: placebo (PL) LoHb (n\u2009=\u200925), PL HiHb (n\u2009=\u200927), hydroxyurea (HU) LoHb (n\u2009=\u200921), and HU HiHb (n\u2009=\u200918).
