  • * Early initiation is defined as initiation in the first 3 days of life; late initiation is defined as initiation after the first 3 days of life.

  • Diarrheal episodes per person-year of follow-up (person-days of actual follow-up in the cited category; number of infants contributing follow-up to the cited category). Note that a given infant could contribute follow-up to more than one cited category within an age interval if the infant's diet changed during the age interval.
