  1. Restricted to children with information on NCATS at 9 months and weight-status at 5.5 years.
  2. aN is unweighted and rounded to the nearest 50. Percents are weighted and 95% confidence intervals account for survey design. Percentages may not total 100% due to rounding.
  3. b P-value from logistic regression models with NCATS score as a continuous variable; P-values for these trends were similar when quartiles were modeled.
