aAdjusted for age, antibiotic prescription, and duration of illness. Analysis for specific organisms was also adjusted for viral co-infection for those with Haemophilus influenzae, and for bacterial co-infection for those with Picornavirus.
bPicornavirus group combines organisms identified as either in Enterovirus genus or Rhinovirus species.
