  • AOM indicates acute otitis media; NS, not significant.

  • * Analysis includes 729 children with complete data on resistance and predictors included in final model.

  • Analysis includes 706 children with complete data on resistance and predictors included in final model.

  • Not significant and therefore not included in final model.
