  • Note: Low coverage rates are calculated using the entire sample; high coverage rates are calculated using only those children with a provider who confirmed that the child was their patient.

  • * Comparison of low and high rates at 3 sites by χ2 test, P < .01.

  • Comparison of low rates at 3 sites by χ2test, P < .01; comparison of high rates at 3 sites by χ2 test not significant.

  • Comparison of low rates at 3 sites by χ2test, P < .01; comparison of high rates at 3 sites by χ2 test, P < .05.
