  • Data are presented as mean ± SD; marginal means adjusting for variables included in P value 1.

  • a P value for the effect modification adjusting for stratified variables only: site, age (5–7 vs 8–10 years old), and overweight (≥85th vs <85th BMI percentile).

  • b P value for the effect modification adjusting for site, age (continuous), obese (<95 vs ≥95 BMI percentile), gender, maternal education (less than high school, high school or higher, or missing/not sure), income (>$30 000, ≤$30 000, or missing), baseline log AHI, and baseline outcome variable.
