Adjusted for median income, sick visits per month, planned additional visits per month, nurse immunization visits per month, chronic illness, race, birth weight category, and Bice score for continuity of care. All AORs are compared with the reference group of 0 missed health supervision visits. CBC, complete blood count; Hct, hematocrit.
