  • Estimates are reported in thousands by convention.59

  • a Proportion of an estimated 143 515 000 average annual visits to pediatricians and general/family practitioners in NAMCS during the study.

  • b Based on estimated antimicrobial prescribing rates from the NAMCS 2000–2010 data.

  • c Proportion of episodes with bacterial cause derived from meta-analysis.

  • d Numbers for all ARTI are based on sums of individual ARTI conditions.

  • e Estimates for individual ARTI in age subgroups sum to fewer than the overall estimates because of rounding.
