Lead Poisoning in Milwaukee: A Medical and Public Health Update.

Over 90% of children in the database had recorded follow-up blood lead testing following an initial elevated blood lead level. There was no difference in initial recorded blood lead levels between children with recorded follow-up blood lead levels and children without (21.40, SD = 11.26); t[1.17], P = 0.24). Most affected children were from economically disadvantaged ZIP codes (53206, 53208, 53215), and 94% lived in rented properties.
