  • a P value for interaction term adjusting stratified variables only: site, race (African American versus non–African American), and age (5–7 vs 8–10 years old).

  • b P value for interaction term adjusting for site, race (African American versus non–African American), age (continuous), gender, maternal education (less than high school, high school or higher, or missing/not sure), income (>$30 000, ≤$30 000, and missing), baseline log AHI, and baseline outcome variable.
