  • CI, confidence interval; OR, odds ratio.

  • a From 3-mo baseline visit.

  • b Represents effect of risk group on odds of higher TV exposure (no TV,1–3 h of TV per day, >3 h of TV per day) in ordered logistic regression, adjusted for infant gender, visit, maternal TV viewing, and clustering by subject.

  • c Fussiness measured only at 3- to 9-mo visits.

  • d Represents effect of risk group on odds of a positive outcome in longitudinal logistic models, adjusted for infant gender, visit, maternal TV viewing, and repeated measures across subjects.
