  • Abbreviations: CBCL, Child Behavior Checklist; MEE, middle-ear effusion.

  • * The term MEE encompasses acute otitis media, secretory otitis media (otitis media with effusion), and tube otorrhea.

  • Mean cumulative proportion of days with MEE (range) was 3.6% (0%–7.2%) for the lowest 25% of study participants; 15.4% (7.2%–24.6%) for the middle 50% of study participants; and 35.7% (24.6%–85.0%) for the highest 25% of study participants.

  • Statistically significant (P ≤ .05) positive Pearson correlation between study participants' scores and their mean cumulative proportion of days with MEE.

  • § Statistically significant (P ≤ .05) negative Pearson correlation between study participants' scores and their mean cumulative proportion of days with MEE.
