Race was not associated with 1A(E), when controlling for the same variables, and center effect was not significant. While children listed 1B(E) increased from 12% to 16% from Era 1 to Era 2, in both eras, Black children were less likely to receive 1B(E) (OR 0.56 [95% CI 0.33 - 0.94) in Era 1, and 0.56 [0.34 - 0.91]) in Era 2).
